NTE7145

NTE7145 Intergrated Circuit 18W BTL x 2 Ch Audio Power Amplifier 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: D 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) D Low Distortion Ratio: THD = 0.04% (Typ) (VCC = 13.2V, f = 1kHz, POUT = 1W, RL = 4Ω, GV = 50dB) D Low Noise: VNO = 0.30mVrms (Typ) (VCC = 13.2V, RL = 4Ω, GV = 50dB, Rg = 0Ω, BW = 20Hz to 20kHz) D Built–In Stand–By Function (With Pin4 set at Low, Power is Turned OFF): ISB = 1µA (Typ) D Built–In Muting Function (With Pin1 set at Low, Power is Turned OFF): V (Mute) = 1V (Typ) D Built–In Various Protection Circuits: Thermal Shut Down Overvoltage OUT→VCC Short OUT→GND Short OUT–OUT Short D Operating Supply Voltage: VCC = 9V to 18V Absolute Maximum Ratings: (TA = +25°C unless otherwise specified) Peak Supply Voltage (0.2s), VCCsurge . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 50V DC Supply Voltage, VCCDC . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 25V OPerating Supply Voltage, VCCopr . . . . . . . . . . . . . . . ...
