Purpose of the product and a brief description of the scope:

The chip is intended for use as a terminal amplifier power in the sound paths of television sets and other consumer electronics, with the possibility of power supply both from network rectifier devices and from autonomous power supplies.

The load of the microcircuit is a dynamic sound reproducing head. Minimum number of attachments, load connection directly to the conclusions of the chip without electrolytic separation large capacitor (the circuit is designed on the principle of a bridge load connections) simplify the use of microcircuits and reduce the overall-equilibrium performance of amplifying sound reproducing devices.

Functions performed:

Audio power amplification with adjustable volume and thermal limitation of the output power.

Composition and structure:

The microcircuit contains:

-input differential stage and volume control unit;

-Voltage regulator;

-Output power amplifier;

-block protection.
