The ADA4692-4 is a quad, rail-to-rail output, single-supply amplifier featuring low power, wide bandwidth, and low noise. 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 and 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 band-width and response for low gain applications. The ADA4692-4 is a quad version without shutdown.
See the ADA4691-4 which has two independent shutdown pins, allowing further reduction in supply current if shutdown required.
The ADA4692-4 is specified over the extended industrial temperature range (−40°C to +125°C). The ADA4692-4 is available in a 14-lead TSSOP.
