NXP Semiconductors Integrated Circuits (ICs) - Data Acquisition - ADCs-DACs - Special Purpose UDA1330ATS/N2,112

The UDA1330ATS is a low-cost stereo digital-to-analog converter (DAC) designed for audio applications, featuring a power supply voltage range of 2.7 to 5.5 V and low power consumption. It supports various sampling frequencies from 8 to 55 kHz and offers multiple digital input formats, including I¬=S-bus and both MSB- and LSB-justified formats with word lengths up to 20 bits. The device can operate in two modes: L3 mode, which allows for digital sound processing control via an interface, and static pin mode, which simplifies operation without the need for the interface. The DAC integrates a digital filter and requires no analog post-filtering, making it suitable for applications such as PC audio and car radios. It provides features like digital volume control, soft mute, and de-emphasis for specific sampling frequencies. The UDA1330ATS is packaged in a compact SSOP16 format, ensuring ease of integration into various designs. Its performance metrics include a signal-to-noise ratio of 95 dB and total harmonic distortion plus noise of -85 dB at 0 dB output, indicating high audio fidelity.
