NTE7186 Integrated Circuit DMOS Audio Amplifier, 100W with Mute/Stand−By Description: The NTE7186 is a monolithic integrated circuit in a 15−Lead Staggered SIP type package, intended for use as audio class AB amplifier in Hi−Fi field applications (Home Stereo, self powered loudspeakers, Top class TV). Thanks to a wide voltage range and to the high out current capability it is able to supply the highest power into both 4Ω and 8Ω loads. The built in muting function with turn on delay simplifies the remote operation avoiding switching on−off noises. Features: D Very High Operating Voltage Range (±50V) D DMOS Power Stage D High Output Power (100W @ THD = 10%, RL = 8Ω, VS = ±40) D Muting/Stand−By Functions D No Switch ON/OFF Noise D Very Low Distortion D Very Low Noise D Short Circuit Protection D Thermal Shutdown D Clip Detector Absolute Maximum Ratings: Supply Voltage (No Signal), VS . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . ±60V VSTAND−BY GND Voltage Referred to −VS (Pin8), V1 . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 90V Input Voltage (Inverting) Referred to −VS, V2 . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 90V Maximum Differential Inputs, V2 − V3 . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . ±30V Input Voltage (Non−Inverting) Referred to −VS, V3 . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 90V Signal GND Voltage Referred to −VS, V4 . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 90V Clip Detector Voltage Referred to −VS, V5 . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 120V Bootstrap Voltage Referred to −VS, V6 . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 120V Stand−by Voltage Referred to −VS, V9 . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 120V Mute Voltage Referred to −VS, V10 . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 120V Buffer Voltage Referred to −VS, V11 . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 120V Bootstrap Loader Voltage Referred to −VS, V12 . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 100V Output Peak Current, Io . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 10A Power Dissipation (TC = +70°C), Ptot . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 50W Operating Ambient Temperature Range, Top . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 0° to +70°C Storange and Junction Temperature, Tstg, Tj . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . +150°C Maximum Thermal Resistance, Junction−to−Case, RthJC . . . . . . . . . . . . . . . . . . . . . . . . . . . . 1.5°C/W Electrical Characteristics: (VS = ±40, RL = 8Ω, Rg = 50Ω; TA = +25°C, f = 1kHz unless otherwise specified) Parameter Symbol Test Conditions Min Typ Max Unit Supply Range (No Signal) VS ±12 − ±50 V Quiescent Current Iq − 30 − mA Input Bias Current ID − 0.3 1 µA Input Offset Voltage VOS −10 − 10 mV Input Offset Current IOS − − 0.2 µA RMS Continuous Output Power PO − 80 − W d = 10% − 100 − W PO = 5W, f = 1kHz − 0.005 − % PO = 0.1 to 50W, f = 20Hz to 15kHz − − 0.1 % Total Harmonic Distortion d d = 1% RL = 4Ω, VS = ±29V Current Limiter Threshold ISC − 6.5 − A Slew Rate SR − 15 − V/µs Open Loop Voltage Gain GV − 80 − dB Closed Loop Voltage Gain (Note 1) GV − 30 − dB Total Input Noise eN A = Curve − 1 − µV f = 20Hz to 20kHz − 2 5 µV 100 − − kΩ f = 100Hz, Vripple = 0.5Vrms − 75 − dB Device Muted − 150 − °C Device Shut Down − 160 − °C Input Resistance Supply Voltage Rejection Thermal Protection Ri SVR TS Stand−By Function (Ref: to Pin1) Stand−By ON Threshold VSTon − − 1.5 V Stand−By OFF Threshold VSToff 3.5 − − V ATTst−by 70 90 − dB Iq st−by − 0.5 − mA Mute ON Threshold VMon − − 1.5 V Mute OFF Threshold VMoff 3.5 − − V ATTmute 60 80 − dB − 10 − % THD = 10% − 40 − % PO = 50W − − 1 µA Stand−By Attenuation Quiescent Current at Stand−By Mute Function (Ref: to Pin 1) Mute Attenuation Clip Detector Duty Cycle Duty ICLEAK THD = 1% RL = 10KΩ to 5V Slave Function Pin 4 (Ref: to Pin 8 −VS) Slave Threshold VSlave − − 1 V Master Threshold VMaster 3 − − V Note 1.
