Analog Devices Inc. MAX74821 Input/Output Operational Amplifiers

Analog Devices MAX74821 Input/Output Operational Amplifiers are precision, low-noise, CMOS, dual rail-to-rail input/output, single-supply amplifiers. The 8-lead MSOP packaged MAX74821 features a very low offset voltage, low input voltage/current noise, and wide signal bandwidth. These amplifiers use Analog Devices' patented DigiTrim® trimming technique, which achieves superior precision without the switching noise associated with chopping or auto-zeroing techniques.

The combination of low offsets, low noise, very low input bias currents, and high speed makes the MAX74821 amplifiers useful in a wide variety of applications. Filters, integrators, photodiode amplifiers, and high impedance sensors all benefit from the combination of performance features. Audio and other AC applications benefit from the wide bandwidth and low distortion. Applications for these amplifiers include optical control loops, portable and loop-powered instrumentation, and audio amplification for portable devices.
