The AD8605, AD8606, and AD86081 are single-supply, rail-to-rail input and output amplifiers with single, dual, or quad rails. They have a very low offset voltage, a low input voltage and current noise, and a broad signal bandwidth. They use the patented DigiTrim® trimming technique developed by Analog Devices, Inc., which achieves superior precision without the use of lasers.

These amplifiers' low offsets, low noise, very low input bias currents, and high speed make them useful in a wide range of applications. The combination of performance features benefits filters, integrators, photodiode amplifiers, and high impedance sensors. The wide bandwidth and low distortion benefit audio and other ac applications. Optical control loops, portable and loop-powered instrumentation, and audio amplification for portable devices are all applications for these amplifiers.
