NTE7113

NTE7113 Integrated Circuit Dual Audio Power Amplifier, 14W BTL Description: The NTE7113 is an integrated circuit in a 16−Lead Staggered SIP type package designed for use as a 14W (13.2V, 4Ω) output power amplifier. Stereo operation is enabled due to incorporating two BTL amplifiers. High reliability is obtained due to incorporating protectors. ON/OFF is enabled even if power is supplied to power supply terminal by applying stand−by circuit. Features: D High Output Power: 14W x 2 D Incorporates Protection Circuits: Temperature, Over−Voltage, VOUT − GND Short, VOUT − VCC Short D Low Shock Noise fromm Power ON/OFF Operation D Fewer External Components D High Stable Operation Absolute Maximum Ratings: (TA = +25°C unless otherwise specified) Supply Voltage (No Signal), VCC . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 24V Peak Supply Voltage (Time = 0.2s), VCC(surge) . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 50V Supply Current, ICC . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 6A Power Dissipation, PD . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 62.5W Operating Ambient Temperature Range, Topr . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . −30° to +75°C Storage Temperature Range, Tstg . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . −55° to +150°C Thermal Resistance, Junction−to−Case, RthJC . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 2°C/W Electrical Characteristics: (VCC = 13.2V, RL = 4Ω, f = 1kHz, TA = +25°C unless otherwise specified) Parameter Quiescent Circuit Current Output Noise Voltage Voltage Gain Total Harmonic Distortion Symbol ICQ Vno Gv THD Test Conditions Vin = 0mV Stand−by Terminal ON Vin = 0mV, Rg = 10kΩ, Note 1 Vin = 5mV Vin = 5mV Vin = 5mV, f = 100Hz Vin = 5mV, f = 10kHz Maximum Output Power (4Ω) PO THD = 10% Min − − − 50.5 − − − 9.0 Typ 120 21 0.6 52.5 0.20 0.26 0.45 12.5 Max 200 − 1.5 54.5 0.75 − − − Unit mA µA mV dB % % % W Note 1. 15Hz to 30kHz (12dB/oct) With Filter Electrical Characteristics (Cont’d): (VCC = 13.2V, RL = 4Ω, f = 1kHz, TA = +25°C unless otherwise specified) Parameter Ripple Rejection Ratio Output Offset Voltage Channel Balance Frequency Characteristics Crosstalk Symbol RR Test Conditions Rg = 0Ω, Vin = 0mV, Ripple = 300mV, f = 120Hz, Note 1 Vin = 5mV Vin = 5mV, −3dB Down Vin = 5mV, Rg = 10kΩ Min 35 −300 −1 − − − Typ 40 0 0 22 21 61 Max − +300 +1 − − − Unit dB mV dB kHz Hz dB VO(offset) Vin = 0mV CB fCH fCL CT Note 1. 15Hz to 30kHz (12dB/oct) With Filter Pin Connection Diagram (Front View) 16 15 14 13 12 11 10 9 8 7 6 5 4 3 2 1 Output Ch 2 GND (Output Ch 2) Output Ch 2 Ripple Filter Input Ch 2 NFB Ch 2 GND (Input) NFB Ch 2 NFB Ch 1 NFB Ch 1 Input Ch 1 Stand−By Output Ch 1 GND (Output Ch 1) Output Ch 1 VCC 1.220 (31.0) 1.102 (28.0) .071 (1.8) R .142 (3.6) D .110 (2.8) .138 (3.5) .535 (13.6) 1 .317 (8.05) 16 .232 (5.9) .492 (12.5) .070 (1.78) .058 (1.47)
