NTE828
Integrated Circuit
Audio Power Amp, 1.5W
Description:
The NTE828 is an audio amplifier in a 14–Lead DIP type package designed for use in medium power
consumer applications. The gain is internally set to 20 to keep external part count low, but the addition
of an external resistor and capacitor between Pin2 and Pin6 will increase the gain to any value up to 200.
The inputs are ground referenced while the output is automatically biased to one half the supply voltage.
Features:
Minimum External Parts
Wide Supply Voltage Range
Ground Referenced Input
Excellent Supply Rejection
Variable Voltage Gain
Self–Centering Output Quiescent Voltage
Low Distortion
Low Voltage Operation, 4V
Applications:
AM–FM Radio Amplifiers
