UMW ADA4692-2ARZ(UMW)

The ADA4692-2 (dual-channel) and ADA4692-4 (quad-channel) are rail-to-rail output, single-supply amplifiers featuring low power consumption, wide bandwidth, and low noise. The ADA4692-4 is the quad-channel version without shutdown functionality. These amplifiers are suitable for a wide range of applications. Audio, filters, photodiode amplifiers, and charge amplifiers can all benefit from their combination of performance and features. Additional applications include portable consumer audio players requiring low noise and low distortion, where they deliver high gain and slew rate response within the audio band at low power consumption. For industrial applications using high-impedance sensors such as pyroelectric and infrared sensors, advantages are provided by their high input impedance, input bias current as low as 0.5 pA, low offset voltage drift, and sufficient bandwidth and response speed for low-gain applications.
