UDA1328T is a multi-channel filter DAC produced by Philips Semiconductors, with multiple format input interfaces, multi-channel DACs, and advanced audio configurations.
The Philips UDA1328T is a single-chip multi-channel DAC employing bitstream conversion techniques. It supports both L3 microcontroller interface mode and static pin control mode, making it suitable for DVD-like applications using 5.1 channel encoded signals.
The device features a 6-channel DAC with power on/off control and digital logarithmic volume control via the L3 interface or static pins. It supports sample frequencies between 5 kHz and 100 kHz (limited to 55 kHz in 768fs mode) and includes advanced audio configuration such as digital silence detection, noise shaping, and output polarity control.
| Power supply voltage (analog) | 2.7 to 3.6 V |
|---|---|
| Power supply voltage (digital) | 2.7 to 3.6 V |
| Analog supply current (6 channels active) | 28 mA |
| Digital supply current | 11 mA |
| Ambient temperature range | -40 to +85 °C |
| Total harmonic distortion plus noise (channels 1 and 2) | ~95 dB at fs = 48 kHz |
| Signal-to-noise ratio (channels 1 and 2) | 106 dB |
| Number of channels | 6-channel DAC |
The device can operate in L3 microcontroller mode or in static pin mode.
The UDA1328T supports sample frequencies between 5 kHz and 100 kHz.
No, no analog post filtering is required for the DAC.
