High-performance 16-bit DAC
  • - n Dynamic Element Matching (DEM)
  • - 4fs or 8fs oversampling
  • - I2S input data format, up to 8fs
  • - TTL compatible inputs
  • - Marked with single crown (TDA1541A/S1 only)
  • - Marked with double crown (TDA1541A/S2 only)


These monolithic integrated dual 16-bit digital-to-analogue converters are specifically designed for use in hi-fi digital audio equipment such as Compact Disc players, digital tape or cassette recorders.
With this range of DACs, the ten lowest bits are derived from a reference current while the six highest bits are generated by time-averaging in the Dynamic Element Matching (DEM) parts. For a full description the DEM technique.
