The MAX74821 is a dual rail-to-rail input and output, single-supply amplifier. The MAX74821 features very low offset voltage, low input voltage and current noise, and wide signal bandwidth. The MAX74821 uses the Analog Devices Inc. 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 this amplifier 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.
The MAX74821 is specified over the extended industrial temperature range (−40°C to +125°C). The MAX74821 dual is available in an 8-lead MSOP package.
