    ... No analog post filtering required Superior signal-to-noise ratio Wide dynamic range (18-bit) Single rail supply (3.4 to 5.5 V). GENERAL DESCRIPTION The TDA1305T is a new generation of filter-DAC which features a unique combination of bitstream and continuous calibration techniques. The converter functions as a ORDERING INFORMATION TYPE NUMBER ...

    ... The dual 5-bit DAC uses the continuous calibration technique. This method, based on charge storage, involves exact duplication of a single reference current source. In the TDA1305T, 32 such current sources plus 1 spare source are continuously calibrated. The spare source is included to allow continuous converter operation. ...
