LM2808N DIP-18

The LM2808 2W sound IF circuit is designed for television and related applications. The circuit is comprised of 2 independent functions: a sound IF and an audio power amplifier. An improved volume control circuit is included, however, so that recovered audio is a linear function of the resistance of the control potentiometer. Audio power amplification is accomplished with circuitry similar to the popular LM380 audio power amplifier, featuring both short circuit and thermal protection.
