Part Details:

TDA7348 Digitally controlled audio processor Features Input multiplexer ­ Three stereo and one mono inputs ­ Selectable input gain for optimal adaptation to different sources Volume control in 0.3db steps including gain up to 20dB Zero crossing mute and direct mute Pause detector with programmable threshold SO-28 Soft mute controlled by software or hardware PIN Bass and treble control Four speaker attenuators ­ Four independent speakers control in 1.25dB steps for balance and fader facilities instead of standard bipolar multipliers, very low ­ Independent mute function distortion and very low noise are obtained Several new features like softmute, zero-crossing mute All functions programmable via serial I2C bus and pause detector are implemented. Description The Soft Mute function can be activated in two ways, either via the serial bus (bit D0, Mute Byte), The TDA7348 is an upgrade of the TDA7318 or directly on pin 22 through an I/O line of the audioprocessor. microcontroller Thanks to the used BIPOLAR/CMOS technology, Very low DC stepping is obtained by use of a very low distortion, low noise and DC-stepping BICMOS technology. are obtained. Due to a highly linear signal processing, using CMOS-switching techniques Order codes Part number Package Packing TDA7348D SO-28 Tube TDA7348D013TR SO-28 Tape and reel
