Abstract :
A 11/12 bit compatible high-voltage D/A converter with output range within 0-40 V is presented. It can endure 50 V high-voltage, consists of input protection circuit, current limit circuits, switch array, and R-2R network. A high voltage device structure has been used. The die size is 5.024×3.898 mm. The converter was fabricated by the p-n junction isolation bipolar process. The result of measurement has shown that it can operate continuously under 50 V voltage. The total conversion time is less than 4.0 μs
