NTE1577
Integrated Circuit
Dual, Low Noise Preamp
w/Auto Reverse
Description:
The NTE1577 is a dual preamplifier with tape autoreverse facilityin a 16–Lead DIP type package de-
signed for the amplification of low level signals in applications requiring very low noise performance, as
stereo cassette players. Each channel consists of two independent amplifiers. The first has a fixed gain
of 30dB while the second one is an operational amplifier optimized for high quality audio application.
Features:
D Very Low Noise
D High Gain
D Large Output Voltage Swing
D Low Distortion
D Tape Autoreverse Facility
D Single Supply Operation
D Short Circuit Protection
D Wide Supply Range
