GENERAL DESCRIPTION

The TDA1313; 1313T is a voltage driven digital-to-analog converter, and is of a new generation of DACs which incorporates the innovative technique of Continuous Calibration (CC). The largest bit-currents are repeatedly generated from one single current reference source. This duplication is based upon an internal charge storage principle having an accuracy which is insensitive to ageing, temperature and process variations.

The TDA1313; 1313T is fabricated in a 1.0 µm CMOS process and features an extremely low power dissipation, small package size and easy application. Furthermore, the accuracy of the intrinsic high coarse-current combined with the implemented symmetrical offset decoding method preclude zero-crossing distortion and ensures high quality audio reproduction. Therefore, the CC-DAC is eminently suitable for use in (portable) digital audio equipment.
