UDA1334ATS is a low power audio DAC with PLL and multiple format data interface from Philips Semiconductors.
The Philips UDA1334ATS is a single-chip 2-channel digital-to-analog converter (DAC) employing bitstream conversion techniques and an on-board Phase Locked Loop (PLL). Designed for low-voltage and low-power portable digital audio equipment, it supports I2S-bus and LSB-justified serial data formats with word lengths up to 24 bits. The device features basic functions such as de-emphasis for 44.1 kHz sampling frequencies and a mute control.
| Power supply voltage | 2.4 to 3.6 V |
|---|---|
| Package type | SSOP16 |
| Output voltage (RMS) | -900 mV |
| Channel separation | -100 dB |
| Power dissipation (audio mode) | 18 mW |
The device supports sample frequencies from 16 to 100 kHz in asynchronous DAC mode.
No, no analog post filtering is required for the DAC due to its inherent filter function.
The reset time should be at least 1 microsecond when the DAC analog supply voltage is less than 1.25 V.
