GENERAL DESCRIPTION
The AD8601, AD8602, and AD8604 are single, dual, and quad
rail-to-rail, input and output, single-supply amplifiers featuring
very low offset voltage and wide signal bandwidth. These amplifiers
use a new, patented trimming technique that achieves superior
performance without laser trimming. All are fully specified to
operate on a 3 V to 5 V single supply.
The combination of low offsets, very low input bias currents,
and high speed make these amplifiers useful in a wide variety
of applications. Filters, integrators, diode amplifiers, shunt
current sensors, and high impedance sensors all benefit from
the combination of performance features. Audio and other ac
applications benefit from the wide bandwidth and low distortion.
For the most cost-sensitive applications, the D grades offer this
ac performance with lower dc precision at a lower price point.
Applications for these amplifiers include audio amplification for
portable devices, portable phone headsets, bar code scanners,
portable instruments, cellular PA controls, and multipole filters.
The ability to swing rail-to-rail at both the input and output
enables designers to buffer CMOS ADCs, DACs, ASICs, and
other wide output swing devices in single-supply systems.

THEORY OF OPERATION
The AD8601/AD8602/AD8604 family of amplifiers are rail-to-rail
input and output, precision CMOS amplifiers that operate from
2.7 V to 5.0 V of the power supply voltage. These amplifiers use
Analog Devices, Inc., DigiTrim® technology to achieve a higher
degree of precision than available from most CMOS amplifiers.
DigiTrim technology is a method of trimming the offset voltage
of the amplifier after it has been assembled. The advantage in post-
package trimming lies in the fact that it corrects any offset voltages
due to the mechanical stresses of assembly. This technology is
scalable and used with every package option, including the 5-lead
SOT-23, providing lower offset voltages than previously achieved in
these small packages.
The DigiTrim process is completed at the factory and does not
add additional pins to the amplifier. All AD860x amplifiers are
available in standard op amp pinouts, making DigiTrim completely
transparent to the user. The AD860x can be used in any precision
op amp application.
The input stage of the amplifier is a true rail-to-rail architecture,
allowing the input common-mode voltage range of the op amp
to extend to both positive and negative supply rails. The voltage
swing of the output stage is also rail-to-rail and is achieved by
using an NMOS and PMOS transistor pair connected in a
common-source configuration. The maximum output voltage
swing is proportional to the output current, and larger currents
limit how close the output voltage can get to the supply rail,
which is a characteristic of all rail-to-rail output amplifiers.
With 1 mA of output current, the output voltage can reach
within 20 mV of the positive rail and within 15 mV of the
negative rail. At light loads of >100 kΩ, the output swings
within ~1 mV of the supplies.
The open-loop gain of the AD860x is 80 dB, typical, with a load
of 2 kΩ. Because of the rail-to-rail output configuration, the gain
of the output stage and the open-loop gain of the amplifier are
dependent on the load resistance. Open-loop gain decreases with
smaller load resistances. Again, this is a characteristic inherent
to all rail-to-rail output amplifiers.
RAIL-TO-RAIL INPUT STAGE
The input common-mode voltage range of the AD860x extends
to both the positive and negative supply voltages. This maximizes
the usable voltage range of the amplifier, an important feature
for single-supply and low voltage applications. This rail-to-rail
input range is achieved by using two input differential pairs, one
NMOS and one PMOS, placed in parallel. The NMOS pair is
active at the upper end of the common-mode voltage range, and
the PMOS pair is active at the lower end.
The NMOS and PMOS input stages are separately trimmed using
DigiTrim to minimize the offset voltage in both differential pairs.
Both NMOS and PMOS input differential pairs are active in a
500 mV transition region, when the input common-mode voltage
is between approximately 1.5 V and 1 V below the positive supply
voltage. The input offset voltage shifts slightly in this transition
region, as shown in Figure 9 and Figure 10 .The common-mode
rejection ratio is also slightly lower when the input common-
mode voltage is within this transition band. Compared to the
Burr-Brown OPA2340UR rail-to-rail input amplifier, shown in
Figure 54, the AD860x, shown in Figure 55, exhibits lower
offset voltage shift across the entire input common-mode
range, including the transition region.

INPUT OVERVOLTAGE PROTECTION
As with any semiconductor device, if a condition could exist
that could cause the input voltage to exceed the power supply,
the device’s input overvoltage characteristic must be considered.
Excess input voltage energizes the internal PN junctions in the
AD860x, allowing current to flow from the input to the supplies.
This input current does not damage the amplifier, provided it is
limited to 5 mA or less. This can be ensured by placing a resistor in
series with the input. For example, if the input voltage could
exceed the supply by 5 V, the series resistor should be at least
(5 V/5 mA) = 1 kΩ. With the input voltage within the supply
rails, a minimal amount of current is drawn into the inputs,
which, in turn, causes a negligible voltage drop across the series
resistor. Therefore, adding the series resistor does not adversely
affect circuit performance.
OVERDRIVE RECOVERY
Overdrive recovery is defined as the time it takes the output of
an amplifier to come off the supply rail when recovering from
an overload signal. This is tested by placing the amplifier in a
closed-loop gain of 10 with an input square wave of 2 V p-p
while the amplifier is powered from either 5 V or 3 V.
The AD860x has excellent recovery time from overload conditions.
The output recovers from the positive supply rail within 200 ns
at all supply voltages. Recovery from the negative rail is within
500 ns at a 5 V supply, decreasing to within 350 ns when the
device is powered from 2.7 V.
POWER-ON TIME
The power-on time is important in portable applications where
the supply voltage to the amplifier may be toggled to shut down
the device to improve battery life. Fast power-up behavior ensures
that the output of the amplifier quickly settles to its final voltage,
improving the power-up speed of the entire system. When the
supply voltage reaches a minimum of 2.5 V, the AD860x settles to
a valid output within 1 µs. This turn-on response time is faster
than many other precision amplifiers, which can take tens or
hundreds of microseconds for their outputs to settle.
USING THE AD8602 IN HIGH SOURCE IMPEDANCE
APPLICATIONS
The CMOS rail-to-rail input structure of the AD860x allows
these amplifiers to have very low input bias currents, typically
0.2 pA. This allows the AD860x to be used in any application
that has a high source impedance or must use large value
resistances around the amplifier. For example, the photodiode
amplifier circuit shown in Figure 56 requires a low input bias
current op amp to reduce output voltage error. The AD8601
minimizes offset errors due to its low input bias current and low
offset voltage.
The current through the photodiode is proportional to the incident
light power on its surface. The 4.7 MΩ resistor converts this current
into a voltage, with the output of the AD8601 increasing at 4.7 V/µA.
The feedback capacitor reduces excess noise at higher frequencies
by limiting the bandwidth of the circuit to

HIGH SIDE AND LOW SIDE, PRECISION CURRENT
MONITORING
Because of its low input bias current and low offset voltage, the
AD860x can be used for precision current monitoring. The true
rail-to-rail input feature of the AD860x allows the amplifier to
monitor current on either the high side or the low side. Using both
amplifiers in an AD8602 provides a simple method for monitoring
both current supply and return paths for load or fault detection.
Figure 57 and Figure 58 demonstrate both circuits.

Voltage drop is created across the 0.1 Ω resistor that is
proportional to the load current. This voltage appears at the
inverting input of the amplifier due to the feedback correction
around the op amp. This creates a current through R1, which
in turn, pulls current through R2. For the low side monitor, the

USING THE AD8601 IN SINGLE-SUPPLY, MIXED
SIGNAL APPLICATIONS
Single-supply, mixed signal applications requiring 10 or more
bits of resolution demand both a minimum of distortion and a
maximum range of voltage swing to optimize performance. To
ensure that the ADCs or DACs achieve their best performance, an
amplifier often must be used for buffering or signal conditioning.
The 750 µV maximum offset voltage of the AD8601 allows the
amplifier to be used in 12-bit applications powered from a 3 V
single supply, and its rail-to-rail input and output ensure no
signal clipping.
Figure 59 shows the AD8601 used as an input buffer amplifier
to the AD7476, a 12-bit, 1 MSPS ADC. As with most ADCs,
total harmonic distortion (THD) increases with higher source
impedances. By using the AD8601 in a buffer configuration, the
low output impedance of the amplifier minimizes THD while
the high input impedance and low bias current of the op amp
minimizes errors due to source impedance. The 8 MHz gain
bandwidth product of the AD8601 ensures no signal attenua-
tion up to 500 kHz, which is the maximum Nyquist frequency
for the AD7476.

PC100 COMPLIANCE FOR COMPUTER AUDIO
APPLICATIONS
Because of its low distortion and rail-to-rail input and output,
the AD860x is an excellent choice for low cost, single-supply
audio applications, ranging from microphone amplification
to line output buffering. Figure 38 shows the total harmonic
distortion plus noise (THD + N) figures for the AD860x. In
unity gain, the amplifier has a typical THD + N of 0.004%, or
−86 dB, even with a load resistance of 600 Ω. This is compliant
with the PC100 specification requirements for audio in both
portable and desktop computers.
Figure 61 shows how an AD8602 can be interfaced with an AC’97
codec to drive the line output. Here, the AD8602 is used as a
unity-gain buffer from the left and right outputs of the AC’97
codec. The 100 µF output coupling capacitors block dc current
and the 20 Ω series resistors protect the amplifier from short
circuits at the jack.

SPICE MODEL
The SPICE macro-model for the AD860x amplifier can be down-
loaded at www.analog.com. The model accurately simulates a
number of both dc and ac parameters, including open-loop gain,
bandwidth, phase margin, input voltage range, output voltage
swing vs. output current, slew rate, input voltage noise, CMRR,
PSRR, and supply current vs. supply voltage. The model is
optimized for performance at 27°C. Although it functions at
different temperatures, it may lose accuracy with respect to the
actual behavior of the AD860x.
