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:
1/2–Watt Power Output (9.0 Vdc Supply, 8–Ohm Load)
High Overall Gain–3.0mV
(rms)
Sensitivity for 1/2–Watt Output
Low Zero–Signal Current Drain–4.0mAdc @ 9.0V typ
Low Distortion–0.5% at 250mW typ
