UDA1334BT is a low power audio DAC from Philips Semiconductors. It supports sampling frequencies from 8KHz to 100KHz. It has an integrated digital filter and a DAC. The system clock and the sampling rate are automatically detected.
The Philips UDA1334BT is an integrated circuit designed as a low-power audio Digital-to-Analog Converter (DAC). It features an integrated digital filter and supports sample frequencies ranging from 8 kHz to 100 kHz. The device operates in slave mode only, requiring the system to provide the system clock and digital audio interface signals.
| Power supply voltage (VDDA/VDDD) | 1.8 to 3.6 V |
|---|---|
| Sampling frequency range | 8 to 100 kHz |
| Signal-to-noise ratio (fs = 44.1 kHz) | -97 dB |
| Total harmonic distortion-plus-noise (fs = 44.1 kHz) | -80 dB |
The device operates in slave mode only, meaning the system must provide the system clock and digital audio interface signals.
No, no analog post filtering is required for the DAC due to its inherent filter function.
