NTE812
Integrated Circuit
Audio Power Amplifier, 1W
Description:
The NTE812 is a monolithic integrated circuit in a 14鈥揕ead DIP type package designed for use in driver
and power amplifier applications at frequencies from 50Hz to 40kHz. This device will deliver up to 1W
RMS output power into an 8鈩?load. The high input impedance and low standby current provide excellent
low鈥損ower audio output performance for portable applications. The high peak current capability can
be utilized for direct driving of complementary power transistors in high power amplifier applications.

Note 1. Voltage values are with respect to network GND terminal.
Note 2. This rating is valid for the condition that all pins are soldered into a printed circuit board with
a 2鈥?x 2鈥?copper layer area of 14 mil thickness. Most of the heat is conducted to the printed
circuit board copper layer through Pin8 (Input GND).
