NTE7041 Integrated Circuit Dual, Audio Power Amplifier, 22W BTL Description: The NTE7041 is an integrated circuit in a 17–Lead SIP type package designed for stereo audio use in car stereo applications. This device has two built–in channels to reduce the characteristic difference between L and R channels. In addition, the NTE7041 contains stand–by and muting functions and includes a variety of protection circuits. Features: D Low Thermal Resistance: Junction–to–Tab = 1.5°C/W (Infinite Heat Sink) D High Power: POUT(1) = 22W/Ch Typ POUT(2) = 19W/Ch Typ D Low Distortion Ratio: THD = 0.04% Typ D Low Noise: VNO = 0.3mVrms Typ D Built–In Stand–By Function: ISB = 1µA Typ D Built–In Muting Function: V(Mute) = 1V Typ D Built–In Protection Circuits: Thermal Shutdown Overvoltage Out → VCC Short Out → GND Short Out–Out Short D Operating Supply Voltage: VCC = 9V to 18V Absolute Maximum Ratings: (TA = +25°C) Peak Supply Voltage (0.2sec), VCCsurge . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 50V DC Supply Voltage, VCCDC . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 25V Operating Supply Voltage, VCCopr . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 18V Peak Output Current, IOpeak . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 9A Power Dissipation, PD . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 50W Operating Temperature Range, Topr . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . –30° to +85°C Storage Temperature Range, Tstg . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . –55° to +150°C Electrical Characteristics: (TA = +25°C, VCC = 13.2V, RL = 4Ω, f = 1kHz unless otherwise specified) Parameter Quiescent Supply Current Output Power Total Harmonic Distortion Symbol Min Typ Max Unit – 120 250 mA POUT(1) VCC = 14.4V, THD = 10% – 22 – W POUT(2) THD = 10% 16 19 – W – 0.04 0.4 % 48 50 52 dB ICCQ THD Test Conditions VIN = 0 POUT = 1W Voltage Gain GV Output Noise Voltage VNO Rg = 0Ω, BW = 20Hz to 20kHz – 0.3 0.7 mVrms Ripple Rejection Ratio RR fripple = 100Hz, Rg = 600Ω 40 54 – dB Input Resistance RIN – 30 – kΩ –0.3 0 +0.3 V – 1 10 µA – 60 – dB 2.5 – VCC V – 1.0 2.0 V Output Offset Voltage Voffset VIN = 0 Current at Stand–By State ISB Crosstalk CT Rg = 600Ω, VOUT = 0dBm Pin4 Control Voltage VSB Stand–By → OFF (Power → ON) Pin1 Control Voltage V(Mute) Mute → ON (Power → OFF) Pin Connection Diagram (Front View) 17 Power VCC2 16 Output 1 15 Output 2 14 GND 1 13 GND 2 12 Output 3 11 Output 4 10 Power VCC1 9 Pre–VCC 8 Ripple 7 Input 2 6 NF 2 5 Pre–GND 4 Stand–By Switch 3 NF 1 2 Input 1 1 Mute Switch 1.440 (36.6) .197 (5.0) 1.180 (30.0) .670 (17.0) .154 (3.9) .550 (14.0) 1 17 .394 (10.0) .197 (5.0) .079 (2.0) .079 (2.0) .101 (2.56)
