GENERAL DESCRIPTION
The ADA4853-1/ADA4853-2/ADA4853-3 are low power, low cost,
high speed, rail-to-rail output op amps with ultralow power disables
that are ideal for portable consumer electronics. Despite their low
price, the ADA4853-1/ADA4853-2/ADA4853-3 provide excellent
overall performance and versatility. The 100 MHz, −3 dB
bandwidth, and 120 V/μs slew rate make these amplifiers well-
suited for many general-purpose, high speed applications.
The ADA4853-1/ADA4853-2/ADA4853-3 voltage feedback op
amps are designed to operate at supply voltages as low as 2.65 V and up
to 5 V using only 1.4 mA of supply current per amplifier. To further
reduce power consumption, the amplifiers are equipped with a disable
mode that lowers the supply current to less than 1.5 μA maximum,
making them ideal in battery-powered applications.
The ADA4853-1/ADA4853-2/ADA4853-3 provide users with a
true single-supply capability, allowing input signals to extend
200 mV below the negative rail and to within 1.2 V of the positive
rail. On the output, the amplifiers can swing within 200 mV of
either supply rail. With their combination of low price, excellent
differential gain (0.2%), differential phase (0.10°), and 0.5 dB flatness
out to 22 MHz, these amplifiers are ideal for video applications.
The ADA4853-1 is available in a 6-lead SC70, the ADA4853-2 is
available in a 16-lead LFCSP_WQ, and the ADA4853-3 is available in
both a 16-lead LFCSP_WQ and a 14-lead TSSOP. The ADA4853-1
temperature range is −40°C to +85°C while the ADA4853-2/
ADA4853-3 temperature range is −40°C to +105°C.

Stresses above those listed under Absolute Maximum Ratings
may cause permanent damage to the device. This is a stress

other conditions above those indicated in the operational
section of this specification is not implied. Exposure to absolute
maximum rating conditions for extended periods may affect
device reliability.
THERMAL RESISTANCE
θJA is specified for the worst-case conditions, that is, θJA is
specified for the device soldered in the circuit board for
surface-mount packages.

Maximum Power Dissipation
The maximum safe power dissipation for the ADA4853-1/
ADA4853-2/ADA4853-3 is limited by the associated rise in
junction temperature (TJ) on the die. At approximately 150°C,
which is the glass transition temperature, the plastic changes its
properties. Even temporarily exceeding this temperature limit
can change the stresses that the package exerts on the die,
permanently shifting the parametric performance of the
amplifiers. Exceeding a junction temperature of 150°C for an
extended period can result in changes in silicon devices,
potentially causing degradation or loss of functionality.
The power dissipated in the package (PD) for a sine wave and a
resistor load is the total power consumed from the supply
minus the load power.
PD = Total Power Consumed − Load Power

RMS output voltages should be considered.
Airflow increases heat dissipation, effectively reducing θJA.
In addition, more metal directly in contact with the package
leads and through holes under the device reduces θJA.
Figure 6 shows the maximum safe power dissipation in the
package vs. the ambient temperature for the 6-lead SC70
(430°C/W), the 14-lead TSSOP (120°C/W), and the 16-lead
LFCSP_WQ (63°C/W) on a JEDEC standard 4-layer board. θJA
values are approximations.

CIRCUIT DESCRIPTION
The ADA4853-1/ADA4853-2/ADA4853-3 feature a high slew
rate input stage that is a true single-supply topology capable of
sensing signals at or below the minus supply rail. The rail-to-
rail output stage can pull within 100 mV of either supply rail
when driving light loads and within 200 mV when driving
150 Ω. High speed performance is maintained at supply
voltages as low as 2.65 V.
HEADROOM CONSIDERATIONS
The ADA4853-1/ADA4853-2/ADA4853-3 are designed for use in
low voltage systems. To obtain optimum performance, it is
useful to understand the behavior of the amplifiers as input and
output signals approach their headroom limits. The input
common-mode voltage range of the amplifier extends from the
negative supply voltage (actually 200 mV below this) to within
1.2 V of the positive supply voltage.
Exceeding the headroom limits is not a concern for any
inverting gain on any supply voltage, as long as the reference
voltage at the positive input of the amplifier lies within the a
input common-mode range of the amplifier.
The input stage is the headroom limit for signals approaching
the positive rail. Figure 50 shows a typical offset voltage vs. the
input common-mode voltage for the ADA4853-1/ADA4853-2/
ADA4853-3 on a 5 V supply. Accurate dc performance is
maintained from approximately 200 mV below the negative
supply to within 1.2 V of the positive supply. For high speed
signals, however, there are other considerations. As the
common-mode voltage gets within 1.2 V of positive supply, the
amplifier responds well but the bandwidth begins to drop as the
common-mode voltage approaches the positive supply. This can
manifest itself in increased distortion or settling time. Higher
frequency signals require more headroom than the lower
frequencies to maintain distortion performance.

For signals approaching the negative supply, inverting gain, and
high positive gain configurations, the headroom limit is the
output stage. The ADA4853-1/ADA4853-2/ADA4853-3 use a
common-emitter output stage. This output stage maximizes the
available output range, limited by the saturation voltage of the
output transistors. The saturation voltage increases with the
drive current that the output transistor is required to supply due
to the collector resistance of the output transistor.
As the saturation point of the output stage is approached, the
output signal shows increasing amounts of compression and
clipping. For the input headroom case, higher frequency signals
require a bit more headroom than the lower frequency signals.
Figure 27 illustrates this point by plotting the typical distortion
vs. the output amplitude.
OVERLOAD BEHAVIOR AND RECOVERY
Input
The specified input common-mode voltage of the ADA4853-1/
ADA4853-2/ADA4853-3 is 200 mV below the negative supply to
within 1.2 V of the positive supply. Exceeding the top limit results
in lower bandwidth and increased rise time. Pushing the input
voltage of a unity-gain follower to less than 1.2 V from the
positive supply leads to an increasing amount of output error as
well as increased settling time. The recovery time from input
voltages 1.2 V or closer to the positive supply is approximately
40 ns; this is limited by the settling artifacts caused by transis-
tors in the input stage coming out of saturation.
The amplifiers do not exhibit phase reversal, even for input
voltages beyond the voltage supply rails. Going more than 0.6 V
beyond the power supplies turns on protection diodes at the
input stage, greatly increasing the current draw of the devices.

APPLICATIONS INFORMATION
SINGLE-SUPPLY VIDEO AMPLIFIER
With low differential gain and phase errors and wide 0.5 dB
flatness, the ADA4853-1/ADA4853-2/ADA4853-3 are ideal
solutions for portable video applications. Figure 51 shows a
typical video driver set for a noninverting gain of +2, where
RF = RG = 1 kΩ. The video amplifier input is terminated into a
shunt 75 Ω resistor. At the output, the amplifier has a series
75 Ω resistor for impedance matching to the video load.
When operating in low voltage, single-supply applications, the
input signal is only limited by the input stage headroom.

POWER SUPPLY BYPASSING
Attention must be paid to bypassing the power supply pins of
the ADA4853-1/ADA4853-2/ADA4853-3. High quality capacitors
with low equivalent series resistance (ESR), such as multilayer
ceramic capacitors (MLCCs), should be used to minimize
supply voltage ripple and power dissipation. A large, usually
tantalum, 2.2 µF to 47 µF capacitor located in proximity to the
ADA4853-1/ADA4853-2/ADA4853-3 is required to provide good
decoupling for lower frequency signals. The actual value is
determined by the circuit transient and frequency requirements.
In addition, 0.1 µF MLCC decoupling capacitors should be
located as close to each of the power supply pins as is physically
possible, no more than ⅛ inch away. The ground returns should
terminate immediately into the ground plane. Locating the bypass
capacitor return close to the load return minimizes ground loops
and improves performance.
LAYOUT
As is the case with all high speed applications, careful attention
to printed circuit board (PCB) layout details prevents associated
board parasitics from becoming problematic. The ADA4853-1/
ADA4853-2/ADA4853-3 can operate at up to 100 MHz; there-
fore, proper RF design techniques must be employed. The PCB
should have a ground plane covering all unused portions of the
component side of the board to provide a low impedance return
path. Removing the ground plane on all layers from the area
near and under the input and output pins reduces stray capacit-
ance. Signal lines connecting the feedback and gain resistors
should be kept as short as possible to minimize the inductance
and stray capacitance associated with these traces. Termination
resistors and loads should be located as close as possible to their
respective inputs and outputs. Input and output traces should
be kept as far apart as possible to minimize coupling (crosstalk)
through the board. Adherence to microstrip or stripline design
techniques for long signal traces (greater than 1 inch) is
recommended. For more information on high speed board
layout, go to www.analog.com to view A Practical Guide to
High-Speed Printed-Circuit-Board Layout.
