Low Power, 3.6 MHz, Low Noise, Rail-to-
Rail Output, Operational Amplifiers
ADA4691-2/ADA4691-4/ADA4692-2/ADA4692-4
The ADA4691/ADA4692 family is fully specified over the extended
industrial temperature range (−40°C to +125°C). e ADA4691-2
is available in a 10-lead LFCSP and a 9-ball WLCSP. The ADA4692-2
is available in an 8-lead SOIC and 8-lead LFCSP. The ADA4691-4 is
available in a 16-lead LFCSP. The ADA4692-4 is available in a 14-lead
TSSOP. For pin configurations, see the Pin Configurations section.
FEATURES

The ADA4691-2/ADA4692-2 are dual and the ADA4691-4/
ADA4692-4 are the quad rail-to-rail output, single-supply
amplifiers featuring low power, wide bandwidth, and low noise.
The ADA4691-2 has two independent shutdown pins, allowing
further reduction in supply current. The ADA4691-4 is a quad
with dual shutdown pins each controlling a pair of amplifiers
and is available in the 16-lead LFCSP. The ADA4692-4 is a quad
version without shutdown.

These amplifiers are ideal for a wide variety of applications.
Audio, filters, photodiode amplifiers, and charge amplifiers, all
benefit from this combination of performance and features.
Additional applications for these amplifiers include portable
consumer audio players with low noise and low distortion that
provide high gain and slew rate response over the audio band at
low power. Industrial applications with high impedance sensors,
such as pyroelectric and IR sensors, benefit from the high
impedance and low 0.5 pA input bias, low offset drift, and
enough bandwidth and response for low gain applications.

1 Input pins have clamp diodes to the supply pins. Limit the input current to
10 mA or less whenever the input signal exceeds the power supply rail by 0.3 V.
2 Differential input voltage is limited to 6 V or the supply voltage, whichever
is less.
1 N/A = not applicable.
ESD CAUTION
Stresses above those listed under Absolute Maximum Ratings
may cause permanent damage to the device. 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 implied. Exposure to absolute
maximum rating conditions for extended periods may affect
device reliability.

SHUTDOWN OPERATION
INPUT PIN CHARACTERISTICS
The ADA4691-2 has a classic CMOS logic inverter input for each
shutdown pin, as shown in Figure 56.

I

Figure 56. CMOS Inverter
DUT OUTPUT
TIME (400µs/DIV)
With slowly changing inputs, the top transistor and bottom
transistor may be slightly on at the same time, increasing the
supply current. This can be avoided by driving the input with
a digital logic output having fast rise and fall times. Figure 57
through Figure 59 show the supply current for both sections
switching simultaneously with rise times of 1 μs, 10 μs, and 1 ms.
Clearly, the rise and fall times should be faster than 10 μs.
Using an RC time constant to enable/disable shutdown is not
recommended.
Figure 59. Shutdown Pin Rise Time = 1 ms
INPUT THRESHOLD
The input threshold is approximately 1.2 V above the V− pin when
operating on ground and 5 V and 0.9 V when operating on 2.7 V
(see Figure 60 and Figure 61). The threshold is relatively stable
over temperature. For operation on split supplies, the logic swing
may have to be level shifted.
