NTE1231 IC Complete 4W TV Sound Channel

Formerly: ECG1231

NTE1231
Integrated Circuit Complete 4 Watt TV Sound Channel

Description:
Capable of carrying out all of the functions of a TV sound channel, the NTE1231 and NTE1231A silicon monolithic integrated circuits consist of a six-stage IF amplifier/limiter, low-pass filter, differential peak detector, DC volume control, regulated power supply, audio preamplifier, and output stage.
The audio power amplifier will deliver 4W of low-distortion audio to a 16Ω load with a supply of 24V. When used with a 12V supply, such as is found in many portable TV sets, these devices will furnish 1.5W to an 8Ω loud speaker.

The NTE1231 is supplied in a quad in-line plastic package with a copper lead frame. This device is designed to use the printed wiring board on which it is mounted for heat dissipation.

The NTE1231A is furnished in a 16-Lead DIP package with heat-sink contact tabs. The webbed lead configuration (Pin4 & Pin5, Pin12 & Pin13) allows an inexpensive heat sink to be easily attached for increased power dissipation capability and yet permits the use of a standard IC socket or printed wiring board hole layout.

Features:
- High Sensitivity
- High AM Rejection
- DC Volume Control
- High Power Output
- Low Distortion
- Wide Operating Voltage Range: 9V to 28V
- Low Quiescent Current Drain
