UDA1344TS is a low power stereo audio codec with DSP features
The Philips UDA1344TS is a single-chip stereo Analog-to-Digital Converter (ADC) and Digital-to-Analog Converter (DAC) employing bitstream conversion techniques. Designed for low-voltage and low-power portable digital audio equipment, it supports sampling frequencies from 8 to 55 kHz and is pin and function compatible with the UDA1340M.
The device features advanced audio configuration including stereo single-ended input and stereo line output. In L3 microcontroller interface mode, it offers Digital Sound Processing (DSP) features such as digital tone control, bass boost, treble, digital dB-linear volume control, and soft mute. It is available in a small SSOP28 package.
