NTE7088 Integrated Circuit Audio Power Amplifier, 18 Watt BTL x 2 Channel Description: The NTE7088 is an integrated circuit in a 17–Lead Staggered SIP type package designed for car audio applications. This device has two built–in channels to reduce the characteristic difference betwee Left and Right channels. In addition, the functions of stand–by and muting, and a variety of protection circuits are included. Features: D Low Thermal Resistance D High Power D Low Distortion Ratio D Low Noise D Built–In Stand–by Function D Built–In Muting Function D Built–In Protection Circuits: Thermal Shutdown, Overvoltage, Out → VCC short, Out → GND short, OUT – OUT short Absolute Maximum Ratings: (TA = +25°C unless otherwise specified) Peak Supply Voltage (0.2sec), VCC surge . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 50V DC Supply Voltage, VCC DC . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 25V Operating Supply Voltage, VCC opr . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 18V Output Current (Peak), IO (peak) . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 9A Power Dissipation, PD . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 50W Operating Temperature Range, Topr . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . –30° to +85°C Storage Temperature Range, Tstg . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . –55° to +150°C Electrical Characteristics: (VCC = 13.2V, RL = 4Ω, f = 1kHz, TA = +25°C unless otherwise specified) Parameter Quiescent Supply Current Output Power Symbol Min Typ Max Unit VIN = 0 – 120 250 mA POUT(1) VCC = 14.4V, THD = 10% – 18 – W POUT(2) THD = 10% 11 15 – W ICCQ Test Conditions Electrical Characteristics (Cont’d): (VCC = 13.2V, RL = 4Ω, f = 1kHz, TA = +25°C unless otherwise specified) Parameter Symbol Total Harmonic Distortion Ratio THD Test Conditions POUT = 1W Min Typ Max Unit – 0.04 0.4 % 48 50 52 dB Voltage Gain GV Output Noise Voltage VNO Rg = 0Ω, BW = 20Hz to 20kHz – 0.3 0.7 nVrms 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 Current at Stand–by State ISB Crosstalk CT Pin4 Control Voltage Pin1 Control Voltage VIN = 0 Rg = 600Ω, VOUT = 0dBm V (SB) Stand–by → OFF (Power → ON) V (MUTE) Mute → ON (Power → OFF) Pin Connection Diagram (Front View) 17 16 15 14 13 12 11 10 9 8 7 6 Power VCC2 Output 2 Output 1 GND 1 GND 2 Output 4 Output 3 Power VCC1 Pre–VCC Ripple Input 2 NF 2 5 4 3 2 1 Pre–GND Stand–By Switch NF 1 Input 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)
