| 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 = +25C 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 +85C Storage Temperature Range, Tstg . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . -55 to +150C Electrical Characteristics: (VCC = 13.2V, RL = 4, f = 1kHz, TA = +25C unless otherwise specified) Parameter Quiescent Supply Current Output Power Symbol ICCQ POUT(1) POUT(2) VIN = 0 VCC = 14.4V, THD = 10% THD = 10% Test Conditions Min - - 11 Typ 120 18 15 Max 250 - - Unit mA W W Electrical Characteristics (Cont'd): (VCC = 13.2V, RL = 4, f = 1kHz, TA = +25C unless otherwise specified) Parameter Total Harmonic Distortion Ratio Voltage Gain Output Noise Voltage Ripple Rejection Ratio Input Resistance Output Offset Voltage Current at Stand-by State Crosstalk Pin4 Control Voltage Pin1 Control Voltage Symbol THD GV VNO RR RIN Voffset ISB CT V (SB) Rg = 600, VOUT = 0dBm Stand-by OFF (Power ON) VIN = 0 Rg = 0, BW = 20Hz to 20kHz fripple = 100Hz, Rg = 600 Test Conditions POUT = 1W Min - 48 - 40 - -0.3 - - 2.5 - Typ 0.04 50 0.3 54 30 0 1 60 - 1.0 Max 0.4 52 0.7 - - +0.3 10 - VCC 2.0 Unit % dB nVrms dB k V A dB V V V (MUTE) Mute ON (Power OFF) Pin Connection Diagram (Front View) 17 16 15 14 13 12 11 10 9 8 7 6 5 4 3 2 1 Power VCC2 Output 2 Output 1 GND 1 GND 2 Output 4 Output 3 Power VCC1 Pre-VCC Ripple Input 2 NF 2 Pre-GND Stand-By Switch NF 1 Input 1 Mute Switch 1.440 (36.6) 1.180 (30.0) .197 (5.0) .154 (3.9) 1 17 .670 (17.0) .550 (14.0) .394 (10.0) .197 (5.0) .079 (2.0) .079 (2.0) .101 (2.56) |
