The UDA1345TS is a low-power audio codec supporting sampling frequencies from 8 to 100 kHz. It features a non-inverting ADC and DAC, as well as digital dB-linear volume control, digital de-emphasis and soft mute for audio processing.
The Philips UDA1345TS is a single-chip stereo Analog-to-Digital Converter (ADC) and Digital-to-Analog Converter (DAC) employing bitstream conversion techniques. It is designed for use in low-voltage, low-power portable digital audio equipment that incorporates recording and playback functions.
The device supports multiple data formats including I2S-bus up to 24 bits, MSB-justified up to 20 bits, and LSB-justified serial formats of 16, 18, and 20 bits. It features a low power consumption with a supply voltage range of 2.4 V to 3.6 V (typical 3.0 V) and includes integrated digital interpolation filters and non-inverting DACs.
