8.1 Overview

The OPA3S2859-EP features dual channel, high-speed, low noise, wide gain bandwidth amplifier with programmable gain switches to offer a compact, easy-to-use device for wideband transimpedance applications, high-speed data acquisition systems, and applications with weak signal inputs that require low-noise and high-gain front ends. Integrated switches allow for multiple gain settings on a single amplifier stage without the need for an additional multiplexer, therefore minimizing board parasitics.

The OPA3S2859-EP is offered in a 4-mm × 4-mm, 24-pin WQFN package that features multiple feedback (FB) pins for different gain options to make simple feedback network connection between the amplifier output and inverting input. The three internally switched feedback paths along with an additional parallel non-switched feedback path allows for up to four selectable gain configurations.
