TDA1388 is a chip that integrates digital filter, DAC and headphone driver, supports I2S-bus and LSB-justified input format, has independent left and right channel soft mute, channel interchange, stereo headphone and line output, etc., which can meet the needs of CD-ROM audio applications.
The Philips TDA1388 is an integrated circuit designed as a bitstream continuous calibration filter-DAC specifically for CD-ROM audio applications. It incorporates an up-sampling digital filter, noise shaper, unique signal processing features, and integrated line and headphone drivers to ensure high sound quality with a wide dynamic range.
The device supports multiple input formats including I2S-bus and LSB-justified serial data inputs with word lengths of up to 20 bits. It provides extensive channel manipulation features such as separate soft mute for left and right channels, channel interchange functions, and monaural capabilities. The TDA1388 includes digital sound processing features like volume control, bass boost, treble adjustment, de-emphasis, and power on/off click prevention circuitry.
