NTE825
Integrated Circuit
Battery Operated Audio Amp
Description:
The NTE825 amplifier is an integrated circuit in a 14鈥揕ead DIP type package optimized for 6V, 7.5V,
and 9V operation into low impedance loads. The gain is internally set at 20 to keep the 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.
