ADA4692-2 Low Power, Wideband, Low Noise, Rail-to-Rail Output, Dual Op Amp
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.
Applications for these amplifiers include consumer audio personal players with low noise and low distortion that provide 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.
