AD8694ARZ

AD8694 is a low cost, quad channel, rail-to-rail output, single-supply amplifier. 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 this device. Applications for this amplifier include power amplifier (PA) controls, laser diode control loops, portable and loop-powered instrumentation, audio amplification for portable devices, and ASIC input and output amplifiers. It is widely used in application such as battery-powered instrumentation, medical instruments, multipole filters, sensors etc.
