Fully Accurate, 12-/14-/16-Bit, Dual, VOUT nanoDAC SPI Interface, 4.5 V to 5.5 V in a TSSOP AD5025/AD5045/AD5065 FEATURES Low power dual 12-/14-/16-bit DAC, ±1 LSB INL Individual voltage reference pins Rail-to-rail operation 4.5 V to 5.5 V power supply Power-on reset to zero scale or midscale Power down to 400 nA @ 5 V 3 power-down functions Per channel power-down Low glitch upon power-up Hardware power-down lockout capability Hardware LDAC with software LDAC override function CLR function to programmable code SDO daisy-chaining option 14-lead TSSOP APPLICATIONS Process controls Data acquisition systems Portable battery-powered instruments Digital gain and offset adjustment Programmable voltage and current sources Programmable attenuators ence buffer is provided on chip. The AD5025/AD5045/AD5065 incorporate a power-on reset circuit that ensures the DAC output powers up zero scale or midscale and remains there until a valid write takes place to the device. The AD5025/AD5045/AD5065 contain a power-down feature that reduces the current consumption of the device to typically 400 nA at 5 V and provides software selectable output loads while in power-down mode. The parts are put into power-down mode over the serial interface. Total unadjusted error for the parts is <2.5 mV. The parts exhibit very low glitch on power-up. The outputs of all DACs can be updated simultaneously using the LDAC function, with the added functionality of user-selectable DAC channels to simultaneously upd……
