Description:

The NTE7145 is a stereo audio power IC in a 17–Lead Staggered SIP type package designed for car audio use. This device has 2 built–in channels to reduce the characteristics difference between L and R channels. In addition, the functions of stand–by, muting, and a variety of protections circuits are involved.

Features:

● High Power:

POUT(1) = 18W (Typ)/Channel (VCC = 14.4V, f = 1kHz, THD = 10, RL = 4Ω)

POUT(2) = 15W (Typ)/Channel (VCC = 13.2V, f = 1kHz, THD = 10, RL = 4Ω)

● Low Distortion Ratio:

THD = 0.04 (Typ) (VCC = 13.2V, f = 1kHz, POUT = 1W, RL = 4Ω, GV = 50dB)

● Low Noise:

VNO = 0.30mVrms (Typ) (VCC = 13.2V, RL = 4Ω, GV = 50dB, Rg = 0Ω, BW = 20Hz to 20kHz)

● Built–In Stand–By Function (With Pin4 set at Low, Power is Turned OFF):

ISB = 1µA (Typ)

● Built–In Muting Function (With Pin1 set at Low, Power is Turned OFF):

V (Mute) = 1V (Typ)

● Built–In Various Protection Circuits:

Thermal Shut Down

Overvoltage

OUT→VCC Short

OUT→GND Short

OUT–OUT Short

● Operating Supply Voltage: VCC = 9V to 18V
