NTE1882 Integrated Circuit Module - AF Power Amp, 100W Min, Dual Power Supplies
Features: D Compact packaging supports slimmer set designs D Simpler heat sink design facilitates thermal design of slim stereo sets D Current mirror circuit application reduces distortion to 0.08%. D Supports addition of electronic circuits for thermal shutdown and load-short protection circuit as well as pop noise muting which occurs when the power supply switch is turned on and off Absolute Maximum Ratings: (TA = 25C unless otherwise specified) Maximum Supply Voltage, VCCmax . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 73V Thermal Resistance, Junction-to-Case, RthJC . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 1.1C/W Junction Temperature, TJ . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . +150C Operating Substrate Temperature, TC . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . +125C Storage Temperature Range, Tstg . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . -30 to +125C Available Time for Shorted Load (VCC = 51V RL = 8, f = 50Hz, PO = 100W), ts . . . . . . . . . 1sec Recommended Operating Conditions: (TA = 25C unless otherwise specified) Recommended Supply Voltage, VCC . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 51V Load Resistance, RL . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 8 Operating Characteristics: (TA = 25C, VCC = 51V, RL = 8, VG = 40dB, Rg = 600, 100k LPF ON, RL (non-inductive)
