GENERAL DESCRIPTION
TDA1311A
The TDA1311A; AT is a voltage-driven digital-to-analog
converter and is new generation of DAC devices 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 which has an accuracy insensitive to ageing,
temperature matching and process variations.
The TDA1311A; AT 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.
