Description

General part information

OPA1S2385 Series

The OPA1S2384 and OPA1S2385 (OPA1S238x) combine high bandwidth, FET-input operational amplifiers with a fast SPST CMOS switch designed for applications that require the tracking and capturing of fast signals.

By providing a 250-MHz gain bandwidth product and rail-to-rail input/output swings in single-supply operation, the OPA1S238x is capable of wideband transimpedance gain and large output signal swing simultaneously. Low input bias current and voltage noise (6 nV/√Hz) make it possible to amplify extremely low-level input signals for maximum signal-to-noise ratio.

The characteristics of the OPA1S238x make this device ideally suited for use as a wideband photodiode amplifier.
