NTE7157
Integrated Circuit
Low Frequency Power Amplifier
Description:
The NTE7157 is an audio power integrated circuit in a 16âLead DIP type package with builtâin two
channels designed for use in a portable radio cassette tape recorder with power ON/OFF switch.
Features:
D High Power:
POUT = 2.5W/Ch Typ (VCC = 9V, RL = 4â¦, f = 1kHz, THD = 10%)
POUT = 3.0W/Ch Typ (VCC = 9V, RL = 3â¦, f = 1kHz, THD = 10%)
D Voltage Gain:
GV = 45.0dB Typ (Rf = 120â¦, f = 1kHz)
GV = 56.5dB Typ (Rf = 0â¦, f = 1kHz)
D Small Quiescent Current: ICCQ = 21mA Typ (VCC = 9V, VIN = 0)
D Ripple Rejection Ratio: RR = â52dB Typ (VCC = 9V, fripple = 100Hz, Rg = 600â¦)
D Crosstalk: CT = â50dB Typ (VCC = 9V, f = 1kHz, Rg = 600â¦)
D Output Noise Voltage: Vno = 0.3mVrms Typ (VCC = 9V, Rg = 10kâ¦, BW = 20Hz to 20kHz)
