TDA8395T/N3,112

Encoders, Decoders, Converters Overview

The TDA8395T/N3,112 is a monolithic single-chip TV sound system designed for integration into television receivers. It combines an FM stereo radio receiver with a high-performance audio amplifier and associated control circuits on a single silicon die. The device features a fully integrated IF section, eliminating the need for external ceramic filters in many applications. Key electrical characteristics include a high signal-to-noise ratio for clear audio reproduction and a built-in mute function to suppress noise during channel changes or power-up sequences. The unit operates within standard voltage ranges typical for consumer electronics, ensuring compatibility with common TV power supplies while maintaining low distortion levels across the audible frequency spectrum.
