Product Summary

The DA1311A 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 of the DA1311A 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 DA1311A is fabricated in a 1.0 μm CMOS process and features an extremely low-power dissipation, small package size and easy application.
