The STMicroelectronics TDA7348D is a digitally controlled audio processor designed for audio systems. It features a flexible input multiplexer supporting three stereo and one mono input, with selectable gain for optimal adaptation to various sources.
Key functionalities include volume control in precise 0.3dB steps with up to 20dB gain, zero crossing mute, direct mute, and a programmable pause detector. The device also incorporates soft mute capabilities, controllable via software or a hardware PIN. For audio output, it provides four independent speaker attenuators, allowing for balance and fader adjustments in 1.25dB steps, along with independent mute functions.
This audio processor operates over a voltage range of 6V to 10.2V and functions within an extended temperature range of -40°C to 85°C. It is housed in a 28-SOIC surface mount package and communicates via an I²C interface, making it suitable for integration into various audio system designs.
The TDA7348D utilizes BIPOLAR/CMOS technology to achieve very low distortion and noise. Its signal processing employs CMOS-switching techniques for high linearity. This processor is an upgrade to the TDA7318, incorporating enhanced features like soft mute and zero-crossing mute.
