LM 381N Low Noise Dual Preamplifier
Description
LM381N dual low-noise preamp
The LM381/LM381A is a dual gain preamplifier. Transmission of low level signals in applications that require optimal noise performance. Each of the two amplifiers is completely independent, with individual internal power supply isolation Pler controls offering 120dB of supply rejection and 60dB of channel separation. Other outstanding features are high gain (112 dB), large output voltage swing (VCC-2V) p-p, and large power bandwidth (75 kHz, 20 Vp-p). The LM381/ LM381A operates from a single supply across the board with a 9V to 40V range. Either differential input or single ended input configurations can be selected. The amplifier is internally compensated with the provision of additional external compensation for narrowband applications.
