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 4 and 8 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 = 8, 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 = +70C), Ptot . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 50W Operating Ambient Temperature Range, Top . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 0 to +70C Storange and Junction Temperature, Tstg, Tj . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . +150C Maximum Thermal Resistance, Junction-to-Case, RthJC . . . . . . . . . . . . . . . . . . . . . . . . . . . . 1.5C/W
