The AD8694ARUZ is a low noise quad CMOS Operational Amplifier with rail-to-rail output. It features low offset and input voltages, low current noise and wide signal bandwidth. The combination of low offset, low noise, very low input bias currents and high speed make this amplifier useful in a wide variety of applications. Filters, integrators, photodiode amplifiers and high impedance sensors all benefit from this combination of performance features. Audio and other AC applications benefit from the wide bandwidth and low distortion of these devices.
