| NTE7165 Integrated Circuit DMOS Audio Amplifier, 100W, for Self - Powered Loudspeakers Description: The NTE7165 is a monolithic integrated circuit in a 15 - Lead Staggered SIP type package designed for use as an audio class AB amplifier in Hi - Fi field applications (Home Stereo, self - powered loudspeakers, Top - Class TV). Thanks to the wide voltage range and to the high output current cazpability it is able to supply the highest power into both 4 and 8 loads even in the presence of poor supply regulation, with high Supply Voltage Rejection. 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 D DMOS Power Stage D High Output Power (Up To 100W Music Power) D Muting/Stand - By Functions D No Switch ON/OFF Noise D No Boucherot Cells D Very Low Distortion D Very Low Noise D Short Circuit Protection D Thermal Shutdown Absolute Maximum Ratings: Supply Voltage (No Signal), VS . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 50V Output Peak Current, IO . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 10A Total Power Dissipation (TC = +70C), Ptot . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 50W Maximum Operating Junction Temperature, TJ . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . +150C Operatring Ambient Temperature Range, TA . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 0 to +70C Maximum Storage Temperature, Tstg . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . +150C Maximum Thermal Resistance, Junction - to - Case, RthJC . . . . . . . . . . . . . . . . . . . . . . . . . . . . 1.5C/W Electrical Characteristics: (TA = +25C, VS = 35V, RL = 8, GV = 30dB, Rg = 50, f = 1kHz unless otherwise specified) Parameter Supply Range Quiescent Current Input Bias Current Input Offset Voltage Input Offset Current RMS Continuous Output Power Symbol VS Iq ID VOS IOS PO d = 0.5% VS = 35V, RL = 8 VS = 31V, RL = 6 VS = 27V, RL = 4 Music Power (RMS), Note 1 IEC268.3 Rules - = 1s t d = 10% VS = 38V, RL = 8 VS = 33V, RL = 6 VS = 29V, RL = 4, Note 2 Total Harmonic Distortion d PO = 5W, f = 1kHz PO = 0.1 to 50W, f = 20Hz to 20kHz VS = 27V, PO = 5W, f = 1kHz RL = 4 PO = 0.1 to 50W, f = 20Hz to 20kHz Slew Rate Open Loop Voltage Gain Closed Loop Voltage Gain Total Input Noise SR GV GV eN fL, fH Ri SVR TS VSTon VSToff ATTst - by Iq st - by VMon VMoff ATTmute f = 100Hz, Vripple = 0.5Vrms A = Curve f = 20Hz to 20kHz Frequency Response ( - 3dB) Input Resistance Supply Voltage Rejection Thermal Shutdown PO = 1W 100 60 Test Conditions Min 10 20 60 60 60 7 24 Typ 30 70 70 70 100 100 100 0.005 0.01 10 80 30 1 2 Max 40 60 500 10 100 0.1 0.1 40 5 Unit V mA nA mV nA W W W V W W % % % % V/s dB dB V V k dB C V V dB mA 20Hz to 20kHz 75 145 - Stand - By Function (Ref: - VS or GND) Stand- By ON Threshold Stand- By OFF Threshold Stand- By Attenuation Quiescent Current at Stand - By Mute Function (Ref: - VS or GND) Mute ON Threshold Mute OFF Threshold Mute Attenuation 3.5 60 80 1.5 V V dB 3.5 70 90 1 1.5 3 Note 1.
