LMH6643Q-Q1 - 75mA Rail-to-Rail Output Amplifiers

Download the LMH6643Q-Q1 datasheet PDF. This datasheet also covers the LMH6642-Q1 variant, as both devices belong to the same 75ma rail-to-rail output amplifiers family and are provided as variant models within a single manufacturer datasheet.

General Description

The LMH664X family true single supply voltage feedback amplifiers offer high speed (130 MHz), low distortion (

62 dBc), and exceptionally high output current (approximately 75 mA) at low cost and with reduced power consumption when compared against existing devices with similar performance.
