1 / 6 page TLH7841 July 1987 LM381LM381A Low Noise Dual Preamplifier General Description The LM381LM381A is a dual preamplifier for the amplifica- tion of low level signals in applications requiring optimum noise performance Each of the two amplifiers is completely independent with individual internal power supply decou- pler-regulator providing 120 dB supply rejection and 60 dB channel separation Other outstanding 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 applications For additional information see AN-64 AN-104 Features Y Low noise 05 mV total input noise Y High gain 112 dB open loop Y Single supply operation Y Wide supply range 9V – 40V Y Power supply rejection 120 dB Y Large output voltage swing (VCC b 2V)p-p Y Wide bandwidth 15 MHz unity gain Y Power bandwidth 75 kHz 20 Vp-p Y Internally compensated Y Short circuit protected Schematic Diagram TLH7841 – 1 C1995 National Semiconductor Corporation RRD-B30M115Printed in U S A |
