LM387 LM387A Low Noise Dual Preamplifier
General Description
The LM387 is a dual preamplifier for the amplification of low
level signals in applications requiring optimum noise per-
formance Each of the two amplifiers is completely indepen-
dent with an internal power supply decoupler-regulator pro-
viding 110 dB supply rejection and 60 dB channel separa-
tion Other outstanding features include high gain (104 dB)
large output voltage swing (V
bandwidth (75 kHz 20 Vp-p) The LM387A is a selected
version of the LM387 that has lower noise in a NAB tape
circuit and can operate on a larger supply voltage The
LM387 operates from a single supply across the wide range
of 9V to 30V the LM387A operates on a supply of 9V to
40V
The amplifiers are internally compensated for gains greater
than 10 The LN387 LM387A is available in an 8-lead dual-
in-line package The LM387 LM387A is biased like the
LM381 See AN-64 and AN-104
