UDA1320ATS is a low cost stereo filter DAC. It features low power consumption, 2.7 to 3.6 V power supply, selectable control via L3 microcontroller interface or via static pin control, 256, 384 and 512fs system clock (fsys), selectable via static pin control, static pin control selectable output format, 32 bit resolution and 16 bit effective number of bits.
The Philips UDA1320ATS is a single-chip non-inverting stereo Digital-to-Analog Converter (DAC) that employs bitstream conversion techniques. Designed for low power consumption and operation with 2.7 to 3.6 V power supplies, it supports sampling frequencies from 16 kHz up to 48 kHz.
The device features an integrated digital filter and noise shaper, eliminating the need for analog post-filtering. It offers two operating modes: L3 mode, where all digital sound processing is controlled via a microcontroller interface, and static pin mode, which allows configuration of system clock, mute, de-emphasis, and input formats through dedicated pins.
| Supply voltage range (analog/digital) | 2.7 to 3.6 V |
|---|---|
| Ambient temperature range | -40 to +85 °C |
| DAC supply current (typical) | 6.5 mA |
| Digital supply current (typical) | 3.0 mA |
| Output voltage (RMS) at 3.3V | 1.0 Vrms |
| Total harmonic distortion plus noise ratio | -90 to -85 dB |
| Signal-to-noise ratio (A-weighted) | -100 to 95 dB |
| Channel separation | -100 dB |
The device supports sampling frequencies from 16 kHz up to 48 kHz.
No, the device includes an integrated digital filter and noise shaper, so no analog post filtering is required.
It supports I2S-bus, MSB-justified (up to 20 bits), and LSB-justified (16, 18, or 20 bits) formats.
