Introduction
TDA7313 audio processor have been used for more than ten years in the industry because of its simplicity, functionality and good parameters like low distortion, low noise. Chip is based on BIPOLAR/CMOS technology and can be used in various applications including car radios, Hi-FI, simple mixers.
TDA7313 chip has 3 external stereo inputs, that allows to multiplex three incoming sound sources, volume control with steps of 1.25dB, Treble and BASS control, Loudness function, Each of four outputs have distinct control that allows to balance outputs. Chip can be controlled via I2C (TWI) interface.
Description
The idea of this project was to construct independent audio processor which can be embedded in any audio system with ability to control settings with simple button interface with menu preview in LCD.
The intent was to cover all audio-processor functionality within LCD menu.
