dac1233x Datasheet

Mixed Signal Cores->0.25um


Features, Applications

The is a CMOS 12Bit D/A converter for general applications. Its maximum conversion rate is 80MSPS and supply voltage is 1.8V single. An external 0.7V voltage reference(VBIAS) and a single resister(RSET) control the full-scale output current.


80MSPS pipeline operation 1.8V CMOS monolithic construction � 0.6LSB differential linearity (typical) � 1.5LSB integral linearity (typical) External voltage reference 12-Bit voltage parallel input
