Description

The TDA1312AT is a voltage driven D/A converter and is a device of a new generation of digital-to-analog converters which embodies the innovative technique of Continuous Calibration (CC). The largest bit-currents are repeatedly generated by one single current reference source. This duplication is based upon an internal charge storage principle having an accuracy insensitive to ageing, temperature matching and process variations.

The TDA1312AT is fabricated in a 1.0 mm 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.
