GENERAL DESCRIPTION
power. Industrial applications with high impedance sensors
such as Pyroelectric sensors and other IR sensors benefit from
high impedance input, low offset drift and enough bandwidth
and response for low gain applications.
The ADA4692-2 is dual, rail-to-rail output, single-supply
amplifiers featuring low power, wide bandwidth, and low noise
ideal for wide variety of applications. Audio preamps, filters, IR
/ photodiode amplifiers, charge amps and high impedance
sensors all benefit from this combination of performance
features.
The ADA4692-2 are specified over the extended industrial
(–40°C to +125°C) temperature range. The ADA4692-2 is a
dual op amp available in 8-lead SOIC and 8-lead LFCSP (2 mm
x 2 mm x 0.55mm).
Applications for these amplifiers include consumer audio
personal players with low noise, distortion while providing
enough gain and slew rate response over the audio band at low

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.
