7.1 Overview

The OPA3S328 features two high-speed, precision amplifiers combined with programmable switches that are designed to offer a compact sensor or optical interface for high resolution analog-to-digital converters (ADCs). Low output impedance with flat frequency characteristics and zero-crossover distortion circuitry enable high linearity over the full input common-mode range, achieving true rail-to-rail input from a 2.2-V to 5.5-V single supply. Integrated switches allow for multiple gain settings on a single amplifier stage without the need for an additional multiplexer device.

In addition to transimpedance applications, the OPA3S328 is flexible with many different application uses for a variety of equipment, such as optical modules, battery testers, medical instrumentation. This device can be used to replace larger transimpedance amplifiers, log amplifiers, programmable gain amplifiers, or programmable active filters.
