Description:

The NTE7157 is an audio power integrated circuit in a 16–Lead DIP type package with built–in two channels designed for use in a portable radio cassette tape recorder with power ON/OFF switch.

Features:

● High Power:

POUT = 2.5W/Ch Typ (VCC = 9V, RL = 4Ω, f = 1kHz, THD = 10)

POUT = 3.0W/Ch Typ (VCC = 9V, RL = 3Ω, f = 1kHz, THD = 10)

● Voltage Gain:

GV = 45.0dB Typ (Rf = 120Ω, f = 1kHz)

GV = 56.5dB Typ (Rf = 0Ω, f = 1kHz)

● Small Quiescent Current: ICCQ = 21mA Typ (VCC = 9V, VIN = 0)

● Ripple Rejection Ratio: RR = –52dB Typ (VCC = 9V, fripple = 100Hz, Rg = 600Ω)

● Crosstalk: CT = –50dB Typ (VCC = 9V, f = 1kHz, Rg = 600Ω)

● Output Noise Voltage: Vno = 0.3mVrms Typ (VCC = 9V, Rg = 10kΩ, BW = 20Hz to 20kHz)

● Stand–By Switch

● Soft Clip

● Built–In Thermal Shut Down Protection Circuit

● Operating Supply Voltage Range: VCC(opr) = 5V to 12V (TA = +25°C)

● Low Popping Noise at Power ON
