GENERAL DESCRIPTION
The ADA4622-1/ADA4622-2 are the next generation of the
AD820 and the AD822 single-supply, rail-to-rail output (RRO),
precision junction field effect transistors (JFET) input op amps.
The ADA4622-1/ADA4622-2 include many improvements
that make them desirable as an upgrade without compromising
the flexibility and ease of use that makes the AD820 and the
AD822 useful for a wide variety of applications.
The input voltage range includes the negative supply and the
output swings rail-to-rail. Input EMI filters increase the signal
robustness in the face of closely located switching noise sources.
The speed, in terms of bandwidth and slew rate, increases along
with a strong output drive to improve settling time performance
and enable the devices to drive the inputs of modern single-ended,
successive approximation register (SAR) analog-to-digital
converters (ADCs).
Rev. B
Voltage noise is reduced; while keeping the supply current the
same as the AD820 and the AD822, broadband noise is reduced by
25%, and 1/f is reduced by half. DC precision in the ADA4622-1/
ADA4622-2 improved from the AD820 and the AD822 with
half the offset and a maximum thermal drift specification added
to the ADA4622-1/ADA4622-2. The common-mode rejection
ratio (CMRR) is improved from the AD820 and the AD822 to
make the ADA4622-1/ADA4622-2 more suitable when used in
noninverting gain and difference amplifier configurations.
The ADA4622-1/ADA4622-2 are specified for operation over the
extended industrial temperature range of −40°C to +125°C and
operates from 5 V to 30 V with specifications at +5 V, ±5 V, and
±15 V. The ADA4622-1 is available in a 5-lead SOT-23 package
and an 8-lead LFCSP package, and the ADA4622-2 is available in
an 8-lead SOIC package, an 8-lead MSOP package, and an 8-lead
LFCSP package.

INPUT CHARACTERISTICS
The ADA4622-1/ADA4622-2 input stage consists of N-channel,
JFETs that provide low offset, low noise, and high impedance.
The minimum input common-mode voltage extends from
−0.2 mV below V− to 1 V less than V+. Driving the input
closer to the positive rail causes loss of amplifier bandwidth
and increased common-mode voltage error. Figure 80 shows
the rounding of the output due to the loss of bandwidth. The
input and output are superimposed.

Figure 81. No Phase Reversal
Because the input stage uses N-channel JFETs, the input current
during normal operation is negative. However, the input bias
current changes direction as the input voltage approaches V+
due to internal junctions becoming forward-biased (see Figure 82).

The ADA4622-1/ADA4622-2 do not exhibit phase reversal for
input voltages up to V+. For input voltages greater than V+, a
10 kΩ resistor in series with the noninverting input prevents
phase reversal at the expense of higher noise (see Figure 81).

The ADA4622-1/ADA4622-2 are designed for 12 nV/√Hz
wideband input voltage noise density and maintain low noise
performance at low frequencies (see Figure 83). This noise
performance, along with the low input current as well as low
current noise, means that the ADA4622-1/ADA4622-2
contribute negligible noise for applications with a source resistance
greater than 10 kΩ and at signal bandwidths greater than 1 kHz.

Input Overvoltage Protection
The ADA4622-1/ADA4622-2 have internal protective circuitry
that allows voltages as high as 0.3 V beyond the supplies applied
at the input of either terminal without causing damage. Use a
current-limiting resistor in series with the input of the ADA4622-1/
ADA4622-2 if the input voltage exceeds 0.3 V beyond the supply
rails of the amplifiers. If the overvoltage condition persists for
more than a few seconds, damage to the amplifiers can result.
The ADA4622-1/ADA4622-2 unique bipolar rail-to-rail output
stage swings within 10 mV of the supplies with no external
resistive load.
The ADA4622-1/ADA4622-2 approximate output saturation
resistance is 24 Ω, sourcing or sinking. Use the output impedance
to estimate the output saturation voltage when driving heavier
loads. As an example, when driving 5 mA, the saturation
voltage from either rail is roughly 120 mV.
If the ADA4622-1/ADA4622-2 output drives hard against the
output saturation voltage, it recovers within 1.2 μs of the input,
returning to the linear operating region of the amplifier (see
Figure 55 and Figure 58).
Capacitive Load Drive Capability
Direct capacitive loads interact with the effective output impedance
of the ADA4622-1/ADA4622-2 to form an additional pole in
the feedback loop of the amplifiers, which causes excessive
peaking on the pulse response or loss of stability. The worst case
condition is when the devices use a single 5 V supply in a unitygain configuration. Figure 85 shows the pulse response of the
ADA4622-1/ADA4622-2 driving 500 pF directly.
For higher input voltages, determine the resistor value by
VIN  VSY
 10 mA
RS
where:
VIN is the input voltage.
VSY is the voltage of either the V+ pin or the V− pin.
RS is the series resistor.
With a very low input bias current of ±1.5 nA maximum up to
125°C, higher resistor values can be used in series with the inputs
without introducing large offset errors. A 1 kΩ series resistor
allows the ADA4622-1/ADA4622-2 to withstand 10 V of
continuous overvoltage and increases the noise by a negligible
amount. A 5 kΩ resistor protects the inputs from voltages as
high as 25 V beyond the supplies and adds less than 10 μV to
the offset voltage of the amplifiers.

SHUTDOWN OPERATION
Use the active low DISABLE input to put the ADA4622-1 into
shutdown mode. When the voltage on the DISABLE input is
less than 1.4 V above the negative supply voltage (V−), the
ADA4622-1 shuts down and consumes only 50 μA to 60 μA
typical. When the voltage on the DISABLE input is more than
1.4 V above the negative supply voltage (V−), or if the DISABLE
input is left floating, the ADA4622-1 powers up. For best
performance, it is recommended that the input voltage level on
the DISABLE input be V− or that the input be left floating. The
ADA4622-1 is still a drop-in replacement for devices with
standard single channel op-amp pinouts because the ADA4622-1
enables when the DISABLE input is left floating. Figure 86
shows a simplified circuit for the DISABLE input.

MAXIMUM POWER DISSIPATION
The maximum power the ADA4622-1/ADA4622-2 can safely
dissipate is limited by the associated rise in junction
temperature. For plastic packages, the maximum safe junction
temperature is 150°C. If this maximum temperature is exceeded,
reduce the die temperature to restore proper circuit operation.
Leaving the device in the overheated condition for an extended
period can result in device burnout. To ensure proper operation, it
is important to observe the Absolute Maximum Ratings and
Thermal Resistance specifications.

WIDEBAND PHOTODIODE PREAMPLIFIER
The ADA4622-1/ADA4622-2 are an excellent choice for
photodiode preamplifier applications. The low input bias current
minimizes the dc error at the output of the preamplifier. In
addition, the high gain bandwidth product and low input
capacitance maximizes the signal bandwidth of the photodiode
preamplifier. Figure 93 shows the ADA4622-1/ADA4622-2 as a
current to voltage (I to V) converter with an electrical model of a

The ADA4622-1/ADA4622-2 can operate from a ±2.5 V to ±15 V
dual supply or a 5 V to 30 V single supply. The ADP7118 and the
ADP7182 are recommended to generate the clean positive and
negative rails for the ADA4622-1/ADA4622-2. Both low dropout
regulators (LDOs) are available in fixed output voltage or
adjustable output voltage versions. To generate the input
voltages for the LDOs, the ADP5070 dc-to-dc switching regulator
is recommended. Figure 90 shows the recommended power
solution configuration for the ADA4622-1/ADA4622-2.

Data Sheet
The following basic transfer function describes the transimpedance
gain of the photodiode preamplifier:
I PHOTO  RF
1  sC F RF
where
IPHOTO is the output current of the photodiode.
The parallel combination of RF and CF sets the signal bandwidth
(see the I to V gain curve in Figure 95).
s refers to the s-plane.
Note that RF must be set so the maximum attainable output
voltage corresponds to the maximum diode output current,
IPHOTO, which allows use of the full output swing. The attainable
signal bandwidth with this photodiode preamplifier is a function
of RF, the gain bandwidth product (fGBP) of the amplifier, and
the total capacitance at the amplifier summing junction, including
CS and the amplifier input capacitance, CD and CM. RF and the
total capacitance produce a pole with loop frequency (fP).

With the additional pole from the amplifier open-loop response,
the two-pole system results in peaking and instability due to an
insufficient phase margin (see Figure 94).

Adding CF creates a zero in the loop transmission that compensates
for the effect of the input pole, which stabilizes the photodiode
preamplifier design because of the increased phase margin. Adding
CF also sets the signal bandwidth (see Figure 95). The signal
bandwidth and the zero frequency are determined by

The frequency response in this case shows about 2 dB of peaking
and 15% overshoot. Doubling CF and halving the bandwidth results
in a flat frequency response with about 5% transient overshoot.
The dominant sources of output noise in the wideband photodiode
preamp design are the input voltage noise of the amplifier, VNOISE,
and the resistor noise due to RF. The gray curve in Figure 95 shows
the noise gain over frequencies for the photodiode preamp.

Figure 96 shows the ADA4622-1/ADA4622-2 configured as

used in conjunction with a photodiode detector with an input
capacitance of 5 pF. Figure 97 shows the transimpedance response
of the ADA4622-1/ADA4622-2 when IPHOTO is 1 μA p-p. The
amplifiers have a bandwidth of 2 MHz when they are maximized
for a 45° phase margin with CF = 2 pF. Note that with the PCB
parasitics added to CF, the peaking is only 0.5 dB, and the
bandwidth is reduced slightly.

PEAK DETECTOR
MULTIPLEXING INPUTS
A peak detector captures the peak value of a signal and
produces an output equal to it. By taking advantage of the dc
precision and super low input bias current of the JFET input
amplifiers, such as the ADA4622-1/ADA4622-2, a highly
accurate peak detector can be built, as shown in Figure 98.
By using the ADA4622-1 DISABLE input, it is possible to
multiplex two inputs to a single output by using the circuit shown
in Figure 99. If the gain configuration or filter configuration of
the two amplifiers is different, and a common single input to
both amplifiers is used, this configuration can control selectable
gain or selectable frequency response at the output.

Figure 99. Multiplexed Input Circuit
Figure 100 shows the output response when multiplexing two
input signals. The input to the first amplifier is a 4 V p-p,
200 kHz sine wave; the input to the second amplifier is an
8 V p-p, 100 kHz sine wave.
The ADA4622-1/ADA4622-2, shown in Figure 98, are a perfect
fit for building a peak detector because U1 requires dc precision
and high output current during fast peaks, and U2 requires low
input bias current (IB) to minimize capacitance discharge between
peaks. A low leakage and low dielectric absorption capacitor, such
as polystyrene or polypropylene, is required for C3. Reversing the
diode directions causes the circuit to detect negative peaks.
OUTPUT
VOLTAGE
Feedback from the output of the U2B (positive peak) through
R6 limits the output voltage of U2A. After detecting the peak,
the output of U2A swings low but is clamped by D2. D3 reverses
bias and the common node of D3, D4, and R7 is held to a voltage
equal to positive peak by R7. The voltage across D4 is 0 V;
therefore, the leakage is small. The bias current of U2B is also
small. With almost no leakage, C3 has a long hold time.
ADA4622-1
13502-298
To detect a positive peak, U2A drives C3 through D3 and drives
D4 until C3 is charged to a voltage equal to the input peak value.

FULL WAVE RECTIFIER
Figure 101 shows the circuit of a full-wave rectifier using two
ADA4622-1 op amps in single-supply operation. The circuit is
composed of a voltage follower (U1) and a second stage amplifier
(U2) that combine the output of the first stage amplifier and the
inverted version of the input signal. U1 follows the input during
the positive half cycle and clamps the negative going input
signal to ground giving a half wave signal at VHW. The following
equation defines the circuit transfer function:
During the input positive half cycle, U1 follows the input so that
VHW = VIN; therefore, VFW = VIN. During the negative half cycle,
U1 clamps the signal to ground so that VHW = 0 V; therefore,
VFW = −(R3/R2) × VIN = −VIN because R3/R2 = 1. Figure 102
shows the input and outputs waveforms from the circuit. The
input is 2 V p-p, 1 kHz sine wave while the circuit is running on
a 5 V single supply.
