GENERAL DESCRIPTION

The ADA4691-2 and ADA4692-2 are dual, 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. These

amplifiers are ideal for a wide variety of applications. Audio

preamps, filters, IR/photodiode amplifiers, charge amps, and

high impedance sensors all benefit from this combination of

performance features.

enough gain and slew rate response over the audio band at low

power. Industrial applications with high impedance sensors,

such as pyroelectric sensors and other IR sensors, benefit from

the high impedance input, low offset drift, and enough

bandwidth and response for low gain applications.

The ADA4691-2 and ADA4692-2 are specified over the extended

industrial temperature range (−40°C to +125°C). The ADA4691-2

is available in a 10-lead LFCSP package, and the ADA4692-2 is

available in an 8-lead SOIC package.

Applications for these amplifiers include consumer audio

personal players with low noise and low distortion that provide
