Integrated Circuit  
Audio Amplifier, 500mW  
Description:  
the NTE745 is a monolithic complementary power amplifier and preamplifier designed to deliver  
1/2–Watt into a loudspeaker with a 3.0mV(rms) typical input. Gain and bandwidth are externally adjust-  
able. Typical applications include portable AM–FM radios, tape recorders, phonographs, and inter-  
coms.  
Features:  
D 1/2–Watt Power Output (9.0 Vdc Supply, 8–Ohm Load)  
D High Overall Gain–3.0mV(rms) Sensitivity for 1/2–Watt Output  
D Low Zero–Signal Current Drain–4.0mAdc @ 9.0V typ  
D Low Distortion–0.5% at 250mW typ  
Electrical Characteristics: (V+ = 9V, RL = 8, f = 1kHz, TA = +25°C unless otherwise specified)
