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 = 8Ω, f = 1kHz, TA = +25°C unless otherwise specified)
