LM387/LM387A Low Noise Dual Preamplifier
General Description
The LM387isa dual preamplifierforthe amplificationoflow
level signalsin applications requiring optimum noise per-
formance. Eachofthetwo amplifiersis completely indepen-
dent,with aninternal power supply decoupler-regulator,pro-
viding 110dB supply rejectionand60dB channel separa-
tion. Other outstanding features include high gain (104dB),
large output voltage swing (VCCb 2V)p-p,and wide power
bandwidth(75 kHz,20 Vp-p). The LM387Aisa selected
versionofthe LM387thathas lower noiseina NAB tape
circuit, andcan operateona larger supply voltage. The
LM387 operates froma single supply acrossthe wide range9Vto 30V,the LM387A operatesona supplyof9Vto
40V.
The amplifiersare internally compensatedfor gains greater
than10.The LN387, LM387Ais availableinan 8-lead dual-
in-line package. The LM387, LM387Ais biased likethe
LM381. See AN-64and AN-104.
