The DIO25582 is a single, dual, and quad rail-to-rail input and output, shutdown option single/dual-supply amplifiers. It features very low offset voltage, low input voltage and current noise, and wide signal bandwidth. The combination of low offsets, low noise, very low input bias currents, and high speed makes these 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. The DIO25582 is specified over the extended industrial temperature range (-40°C to 125°C). The DIO25582 (dual) is available in an 8-lead MSOP, a 8-lead WLCSP, a 10-lead SOP and an 8-lead DFN package.
