NTE7059

NTE7059 Integrated Circuit Dual BTL 14W Audio Power Amplifier Description: The NTE7059 is an integrated circuit in a 16−Lead Staggered SIP type package designed for 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 the power supply pin by applying stand−by circuit. Features: D High Output Power: 14W x 2 D Incorporates Protection Circuits: Temperature, Overvoltage, VOUT−GND Short, RL Short, VOUT−VCC Short D Low Shock Noise from Power ON/OFF Operation D Fewer External Components D High Stable Operation Absolute Maximum Ratings: (TA = +25°C) Supply Voltage (No Signal), VCC . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 24V Peak Supply Voltage (Time = 0.2s), VCC(surge) . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 50V Supply Current, ICC . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 6A Power Dissipation (RthJC = 2°C/W), PD . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 62.5W Operating Ambient Temperature Range, Topr . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . −30° to +75°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 Circuit Current Output Noise Voltage Voltage Gain Total Harmonic Distortion Maximum Output Power (4Ω) Symbol ICQ Vno GV THD PO Test Conditions Vin = 0mV Vin = 0mV, Rg = 10kΩ, Note 1 Vin = 5mV Vin = 5mV THD = 10% Min − − − 9.0 Typ 120 0.6 Max Unit 200 1.5 mA mV dB % W 50.0 52.5 54.5 0.20 0.75 12.5 − 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 Total Harmonic Distortion Frequency Characteristics Quiescent Circuit Current at Stand−by Pin ON Crosstalk Symbol RR VO(offset) CB THD fCH fCL Test Conditions Rg = 0Ω, Vin = 0mV, Ripple = 300mV, 120Hz, Note 1 Vin = 0mV Vin = 5mV Vin = 5mV, 100Hz Vin = 5mV, 10Hz Vin = 5mV, −3dB down Vin = 5mV, −3dB down Min 35 −300 −1 − − − − − − Typ 40 0 0 0.26 0.45 22 21 21 61 Max Unit − dB +300 mV +1 − − − − − − dB % % kHz Hz μA dB ICQ(STBY−ON) Stand−by Pin ON CT Vin = 5mV, Rg = 10kΩ Note 1. 15Hz to 30kHz (12dB/oct) With Filter Pin Connection Diagram 16 Ch 2 Output 15 GND (Output Ch 2) 14 Ch 2 Output 13 Ripple Filter 12 Ch 2 Input 11 Ch 2 N.F.B. 10 GND (Input) Front View 9 8 7 6 5 4 3 2 Ch 2 N.F.B.
