LM 382N Low Noise Dual Preamplifier
Description
LM382N Low Noise Dual Preamplifier
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.
