LMH6646 - Rail-to-Rail Input and Output voltage feedback Amplifiers

Download the LMH6646 datasheet PDF. This datasheet also covers the LMH6645 variant, as both devices belong to the same rail-to-rail input and output voltage feedback amplifiers family and are provided as variant models within a single manufacturer datasheet.

General Description

The LMH6645 (single) and LMH6646 (dual), rail-torail input and output voltage feedback amplifiers, offer high speed (55 MHz), and low voltage operation (2.7 V) in addition to micro-power shutdown capability (LMH6647, single).

Key Features
