The AD5025 / AD5045 / AD5065 are low power, dual 12-/14-/16-bitbuffered voltage output nanoDAC® DACs offering relative accuracyspecifications of ±1 LSB INL with individual reference pins, andcan operate from a single 4.5 V to 5.5 V supply. The AD5025 /AD5045 / AD5065 also offer a differential accuracy specification of±1 LSB. The parts use a versatile 3-wire, low power Schmitttrigger serial interface that operates at clock rates up to 50 MHzand is compatible with standard SPI®, QSPI™, MICROWIRE™,and DSP interface standards. The reference for the AD5025 /AD5045 / AD5065 are supplied from an external pin and a reference buffer is provided on chip. The AD5025 / AD5045 / AD5065incorporate a power-on reset circuit that ensures the DAC outputpowers up zero scale or midscale and remains there until a validwrite takes place to the device. The AD5025 / AD5045 / AD5065contain a power-down feature that reduces the current consumptionof the device to typically 400 nA at 5 V and provides softwareselectable output loads while in power-down mode. The parts areput into power-down mode over the serial interface. Total unadjustederror for the parts is <2.5 mV. The parts exhibit very lowglitch on power-up. The outputs of all DACs can be updatedsimultaneously using the LDAC function, with the addedfunctionality of user-selectable DAC channels to simultaneouslyupdate. There is also an asynchronous CLR that clears all DACsto a software-selectable code—0 V, midscale, or full scale. Theparts also feature a power-down lockout pin, PDL, which can beused to prevent the DAC from entering power-down under anycircumstances over the serial interface.
