LM382 Low Noise Dual Preamplifier
General Description
The LM382 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 individual internal power supply decoupler-regula-
tor, providing 120 dB supply rejection and 60 dB channel
separation. Other outstanding features include high gain
(100 dB), and wide power bandwidth (75 kHz, 20 Vp-p). The
LM382 operates from a single supply across the wide range
of 9V to 40V.
A resistor matrix is provided on the chip to allow the user to
select a variety of closed loop gain options and frequency
response characteristics such as flat-band, NAB or RIAA
equalization. The circuit is supplied in the 14 lead dual-in-
line package.
