GENERAL DESCRIPTION
The AD825 is a superbly optimized operational amplifier for
high speed, low cost, and dc parameters, making it ideally suited
for a broad range of signal conditioning and data acquisition
applications. The ac performance, gain, bandwidth, slew rate,
and drive capability are all very stable over temperature. The
AD825 also maintains stable gain under varying load
conditions.
The unique input stage has ultralow input bias current and
input current noise. Signals that go to either rail on this high
performance input do not cause phase reversals at the output.
These features make the AD825 a good choice as a buffer for
MUX outputs, creating minimal offset and gain errors.
The AD825 is fully specified for operation with dual ±5 V and
±15 V supplies. This power supply flexibility, and the low supply
current of 6.5 mA with excellent ac characteristics under all
supply conditions, makes the AD825 well-suited for many
demanding applications.

ESD CAUTION
ESD (electrostatic discharge) sensitive device. Electrostatic charges as high as 4000 V readily accumulate on
the human body and test equipment and can discharge without detection. Although this product features
proprietary ESD protection circuitry, permanent damage may occur on devices subjected to high energy
electrostatic discharges. Therefore, proper ESD precautions are recommended to avoid performance
degradation or loss of functionality.

THEORY OF OPERATION
The AD825 is a low cost, wideband, high performance FET
input operational amplifier. With its unique input stage design,
the AD825 ensures no phase reversal, even for inputs that
exceed the power supply voltages, and its output stage is
designed to drive heavy capacitive or resistive loads with small
changes relative to no load conditions.
The AD825 (Figure 32) consists of common-drain, common-
base FET input stage driving a cascoded, common-base
matched NPN gain stage. The output buffer stage uses emitter
followers in a Class AB amplifier that can deliver large current
to the load while maintaining low levels of distortion.

Figure 32. Simplified Schematic
The capacitor, CF, in the output stage, enables the AD825 to
drive heavy capacitive loads. For light loads, the gain of the
output buffer is close to unity, CF is bootstrapped, and not much
happens. As the capacitive load is increased, the gain of the
output buffer is decreased and the bandwidth of the amplifier is
reduced through a portion of CF adding to the dominant pole.
As the capacitive load is further increased, the amplifier’s
bandwidth continues to drop, maintaining the stability of the
AD825.
INPUT CONSIDERATION
The AD825 with its unique input stage ensures no phase
reversal for signals as large as or even larger than the supply
voltages. Also, layout considerations of the input transistors
ensure functionality even with a large differential signal.
The need for a low noise input stage calls for a larger FET
transistor. One should consider the additional capacitance that
is added to ensure stability. When filters are designed with the
AD825, one needs to consider the input capacitance (5 pF to
6 pF) of the AD825 as part of the passive network.
GROUNDING AND BYPASSING
The AD825 is a low input bias current FET amplifier. Its high
frequency response makes it useful in applications, such as
photodiode interfaces, filters, and audio circuits. When
designing high frequency circuits, some special precautions are
in order. Circuits must be built with short interconnects, and
resistances should have low inductive paths to ground. Power
supply leads should be bypassed to common as close as possible
to the amplifier pins. Ceramic capacitors of 0.1 µF are
recommended.
AD825
Rev. F | Page 11 of 12
SECOND-ORDER LOW-PASS FILTER
A second-order Butterworth low-pass filter can be implemented
using the AD825 as shown in Figure 33. The extremely low bias
currents of the AD825 allow the use of large resistor values and,
consequently, small capacitor values without concern for
developing large offset errors. Low current noise is another
factor in permitting the use of large resistors without having to
worry about the resultant voltage noise.
With the values shown, the corner frequency will be 1 MHz.
The equations for component selection are shown below. Note
that the noninverting input (and the inverting input) has an
input capacitance of 6 pF. As a result, the calculated value of C1
(12 pF) is reduced to 6 pF.
