The UDA1330ATS is a single-chip stereo DAC employing bitstream conversion techniques.

The UDA1330ATS supports the I²S-bus data format with word lengths of up to 20 bits, the MSB-justified data format with word lengths of up to 20 bits and the LSB-justified serial data format with word lengths of 16, 18 and 20 bits.

The UDA1330ATS can be used in two modes: L3 mode or the static pin mode.

In the L3 mode, all digital sound processing features must be controlled via the L3 interface, including the selection of the system clock setting.

In the two static modes, the UDA1330ATS can be operated in the 256fs and 384fs system clock mode. Muting, de-emphasis for 44.1 kHz and four digital input formats (I²S-bus or LSB-justified 16, 18, and 20 bits) can be selected via static pins. The L3 interface cannot be used in this application mode, so volume control is not available in this mode.

Features and benefits

General

  • Low power consumption
  • Power supply voltage from 2.7 to 5.5 V
  • Selectable control via L3 microcontroller interface or via static pin control
  • System clock frequencies of 256fs, 384fs and 512fs selectable via L3 interface or 256fs and 384fs via static pin control
  • Supports sampling frequencies (fs) from 8 to 55 kHz
  • Integrated digital filter plus non inverting
  • Digital-to-Analog Converter (DAC)
  • No analog post filtering required for DAC
  • Slave mode only applications
  • Easy application
  • Small package size (SSOP16)
  • TTL tolerant input pads
  • Pin and function compatible with the UDA1320ATS.

Multiple format input interface

  • L3 mode: I²S-bus, MSB-justified or LSB-justified 16, 18 and 20 bits format compatible
  • Static pin mode: I²S-bus and LSB-justified 16, 18 and 20 bits format compatible
  • 1fs input format data rate.

DAC digital sound processing

  • Digital logarithmic volume control in L3 mode
  • Digital de-emphasis for 32, 44.1 and 48 kHz sampling frequencies in L3 mode or 44.1 kHz sampling frequency in static pin mode
  • Soft mute control both in static pin mode and L3 mode.

Advanced audio configuration

  • Stereo line output (volume control in L3 mode)
  • High linearity, wide dynamic range and low distortion.

Applications

  • PC audio applications
  • Car radio applications.
