UDA1330ATS is a low-cost stereo filter DAC with features including low power consumption, selectable control, support for multiple sampling frequencies, integrated digital filter, and non-inverting DAC.
The UDA1330ATS is a single-chip stereo Digital-to-Analog Converter (DAC) employing bitstream conversion techniques. It supports sampling frequencies from 16 to 55 kHz and operates in slave mode only, requiring an external system clock.
The device features two application modes: L3 mode for full digital control via an interface, and static pin mode for simpler configurations. It includes integrated digital filtering, a noise shaper, and a Filter Stream DAC (FSDAC) that eliminates the need for analog post-filtering.
| Power supply voltage (DAC analog) | 2.7 to 5.5 V |
|---|---|
| Ambient temperature range | -40 to +85 °C |
| Output voltage (RMS) at 5.0 V supply | 1.45 V typ. |
| Signal-to-noise ratio (code = 0) | -95 dB typ. |
| Channel separation | 100 dB |
The device supports sampling frequencies from 16 to 55 kHz.
No, no analog post filtering is required for the DAC due to its inherent filter function.
In L3 mode, the selectable system clock frequencies are 256fs, 384fs, and 512fs.
