NTE812 Single-Channel Audio Power-Output Amplifier DIP-14
Formerly: ECG812
Integrated Circuit
Audio Power Amplifier, 1W
Description:
The NTE812 is a monolithic integrated circuit in a 14-Lead 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 Ohm load. The high input impedance and low standby current provide excellent low-power 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.
Features:
- 1 Watt RMS Power into 8 Ohm with THD = 0.65% Typ
- Peak Output Current: 1A
- Wide Supply Voltage Range: 4V to 13V
- High Input Impedance
Applications:
- Radios
- Phonographs
- Portable Communications Receivers
- Complementary Power Amplifiers Drivers
- Servo Drivers
