General Description

The LM381 LM381A is a dual preamplifier for the amplification of low level signals in applications requiring optimum noise performance Each of the two amplifiers is completely independent with individual internal power supply decoupler-regulator providing 120 dB supply rejection and 60 dB channel separation Other outstanding

Overview

LM381 LM381A Low Noise Dual Preamplifier July 1987 LM381 LM381A Low Noise Dual.

Key Features

include high gain (112 dB) large output voltage swing (VCC b 2V) p-p and wide power bandwidth (75 kHz 20 Vp-p) The LM381 LM381A operates from a single supply across the wide range of 9V to 40V Either differential input or single ended input configurations may be selected The amplifier is internally compensated with the provision for additional external compensation for narrow band.
