GENERAL DESCRIPTION
The AD822 is a dual precision, low power FET input op amp
that can operate from a single supply of 5 V to 30 V or dual
supplies of ±2ꢀ5 V to ±±5 Vꢀ It has true single-supply capability
with an input voltage range extending below the negative rail,
allowing the AD822 to accommodate input signals below
ground in the single-supply modeꢀ Output voltage swing
extends to within ±0 mV of each rail, providing the maximum
output dynamic rangeꢀ
Good dc performance
800 μV maximum input offset voltage
2 μV/°C typical offset voltage drift
25 pA maximum input bias current
Low noise
13 nV/√Hz @ 10 kHz
No phase inversion

APPLICATIONS
Battery-powered precision instrumentation
Photodiode preamps
Active filters
12-bit to 14-bit data acquisition systems

Figure 2. Input Voltage Noise vs. Frequency
Offset voltage of 800 μV maximum, offset voltage drift of 2 μV/°C,
input bias currents below 25 pA, and low input voltage noise
provide dc precision with source impedances up to a gigaohmꢀ
The ±ꢀ8 MHz unity-gain bandwidth, –93 dB THD at ±0 kHz,
and 3 V/μs slew rate are provided with a low supply current of
800 μA per amplifierꢀ

AD822
The AD822 drives up to 350 pF of direct capacitive load as a
follower and provides a minimum output current of ±5 mAꢀ
This allows the amplifier to handle a wide range of load conditionsꢀ
Its combination of ac and dc performance, plus the outstanding
load drive capability, results in an exceptionally versatile amplifier
for the single-supply userꢀ

1 This is a functional specification. Amplifier bandwidth decreases when the input common-mode voltage is driven in the range (V+ − 1 V) to V+. Common-mode error
voltage is typically less than 5 mV with the common-mode voltage set at 1 V below the positive supply.
2 VOL − VEE is defined as the difference between the lowest possible output voltage (VOL) and the negative voltage supply rail (VEE). VCC − VOH is defined as the difference
between the highest possible output voltage (VOH) and the positive supply voltage (VCC).

1 This is a functional specification. Amplifier bandwidth decreases when the input common-mode voltage is driven in the range (V+ − 1 V) to V+. Common-mode error
voltage is typically less than 5 mV with the common-mode voltage set at 1 V below the positive supply.
2 VOL − VEE is defined as the difference between the lowest possible output voltage (VOL) and the negative voltage supply rail (VEE). VCC − VOH is defined as the difference
between the highest possible output voltage (VOH) and the positive supply voltage (VCC).

MAXIMUM POWER DISSIPATION
The maximum power that can be safely dissipated by the
AD822 is limited by the associated rise in junction temperatureꢀ
For plastic packages, the maximum safe junction temperature is
±45°Cꢀ If these maximums are exceeded momentarily, proper
circuit operation is restored as soon as the die temperature is
reducedꢀ Leaving the device in the overheated condition for an
extended period can result in device burnoutꢀ To ensure proper
operation, it is important to observe the derating curves shown
in Figure 27ꢀ
–40°C to +85°C
260°C
Lead Temperature
(Soldering, 60 sec)
1 See the Input Characteristics section.
Stresses above those listed under Absolute Maximum Ratings
may cause permanent damage to the deviceꢀ This is a stress
rating only; functional operation of the device at these or any
other conditions above those indicated in the operational
section of this specification is not impliedꢀ Exposure to absolute
maximum rating conditions for extended periods may affect
device reliabilityꢀ
While the AD822 is internally short-circuit protected, this may
not be sufficient to guarantee that the maximum junction
temperature is not exceeded under all conditionsꢀ With power
supplies ±±2 V (or less) at an ambient temperature of 25°C or
less, if the output node is shorted to a supply rail, then the
amplifier is not destroyed, even if this condition persists for an
extended periodꢀ

INPUT CHARACTERISTICS
WHENEVER JOHNSON NOISE IS GREATER THAN
AMPLIFIER NOISE, AMPLIFIER NOISE CAN BE
CONSIDERED NEGLIGIBLE FOR APPLICATION.
In the AD822, N-channel JFETs are used to provide a low offset,
low noise, high impedance input stageꢀ Minimum input common-
mode voltage extends from 0ꢀ2 V below −VS to ± V less than +VSꢀ
Driving the input voltage closer to the positive rail causes a loss
of amplifier bandwidth (as can be seen by comparing the large
signal responses shown in Figure 34 and Figure 37) and increased
common-mode voltage error as illustrated in Figure 20ꢀ

The AD822 does not exhibit phase reversal for input voltages
up to and including +VSꢀ Figure 42 shows the response of an
AD822 voltage follower to a 0 V to 5 V (+VS) square wave inputꢀ
The input and output are superimposedꢀ The output tracks the
input up to +VS without phase reversalꢀ The reduced bandwidth
above a 4 V input causes the rounding of the output waveformꢀ
For input voltages greater than +VS, a resistor in series with the
AD822 noninverting input prevents phase reversal, at the expense
of greater input voltage noiseꢀ This is illustrated in Figure 42ꢀ

Figure 43. Total Noise vs. Source Impedance
OUTPUT CHARACTERISTICS
The AD822 unique bipolar rail-to-rail output stage swings within
5 mV of the negative supply and ±0 mV of the positive supply with
no external resistive loadꢀ The approximate output saturation
resistance of the AD822 is 40 Ω sourcing and 20 Ω sinking, which
can be used to estimate output saturation voltage when driving
heavier current loadsꢀ For instance, when sourcing 5 mA, the
saturation voltage to the positive supply rail is 200 mV; when
sinking 5 mA, the saturation voltage to the negative rail is ±00 mVꢀ
Because the input stage uses N-channel JFETs, input current
during normal operation is negative; the current flows out from
the input terminalsꢀ If the input voltage is driven more positive
than +VS − 0ꢀ4 V, then the input current reverses direction as
internal device junctions become forward biasedꢀ This is illu-
strated in Figure 7ꢀ
A current limiting resistor should be used in series with the input
of the AD822 if there is a possibility of the input voltage exceed-
ing the positive supply by more than 300 mV, or if an input voltage
is applied to the AD822 when +VS or −VS = 0 Vꢀ The amplifier is
damaged if left in that condition for more than ±0 secondsꢀ A ± kΩ
resistor allows the amplifier to withstand up to ±0 V of conti-
nuous overvoltage and increases the input voltage noise by a
negligible amountꢀ
The open-loop gain characteristic of the amplifier changes as a
function of resistive load, as shown in Figure ±0 to Figure ±3ꢀ
For load resistances over 20 kΩ, the AD822 input error voltage
is virtually unchanged until the output voltage is driven to ±80 mV
of either supplyꢀ
If the AD822 output is overdriven so that either of the output
devices are saturated, the amplifier recovers within 2 ꢁs of its
input returning to the linear operating region of the amplifierꢀ
Input voltages less than −VS are a completely different storyꢀ The
amplifier can safely withstand input voltages 20 V below the
negative supply voltage if the total voltage from the positive
supply to the input terminal is less than 36 Vꢀ In addition, the
input stage typically maintains picoampere (pA) level input
currents across that input voltage rangeꢀ
Direct capacitive loads interact with the effective output imped-
ance of the amplifier to form an additional pole in the amplifier
feedback loop, which can cause excessive peaking on the pulse
response or loss of stabilityꢀ The worst case occurs when the
amplifier is used as a unity-gain followerꢀ Figure 44 shows the
AD822 pulse response as a unity-gain follower driving 350 pFꢀ
This amount of overshoot indicates approximately 20° of phase
margin—the system is stable, but nearing the edgeꢀ Configurations
with less loop gain, and as a result less loop bandwidth, are
much less sensitive to capacitance load effectsꢀ
The AD822 is designed for ±3 nV/√Hz wideband input voltage
noise and maintains low noise performance to low frequencies
(refer to Figure ±4)ꢀ This noise performance, along with the
AD822 low input current and current noise, means that the
AD822 contributes negligible noise for applications with source
resistances greater than ±0 kΩ and signal bandwidths greater
than ± kHzꢀ This is illustrated in Figure 43ꢀ
Rev. I | Page 18 of 24

Figure 46 shows a method for extending capacitance load drive
capability for a unity-gain followerꢀ With these component
values, the circuit drives 5000 pF with a ±0% overshootꢀ
