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

Absolute Maximum Ratings: (T_A = +25°C unless otherwise specified)

Supply Voltage (Note 1), VCC		15V
Output Current, IO		1A
Continuous Power Dissipation (TA </= +25°, Note 2), PD		1.1W
Derate Above 25¥C		14.7mW/¥C
Operating Temperature Range, Topr		-55°C to +100°C
Storage Temperature Range, Tstg		-65°C to +150°C
Lead Temperature (During Soldering, 1/16" from case, 10sec), TL		+260°C

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" x 2" copper layer of 14 mil thickness. Most of the heat is conducted to the printed circuit board copper layer through Pin8 (Input GND).
