The AD5024/AD5044/AD5064/AD5064-1 are low power, quad 12-/14-/16-bit buffered voltage output nanoDAC® converters that offer relaTIve accuracy specificaTIons of 1 LSB INL and 1 LSB DNL with the AD5024/AD5044/AD5064 individual reference pin and the AD5064-1 common reference pin opTIons. The AD5024/AD5044/AD5064/AD5064-1 can operate from a single 4.5 V to 5.5 V supply. The AD5024/AD5044/AD5064/AD5064-1 also offer a differenTIal accuracy specification of ±1 LSB. The parts use a versatile 3-wire, low power Schmitt trigger serial interface that operates at clock rates up to 50 MHz and is compati-ble with standard SPI, QSPI™, MICROWIRE™, and DSP interface standards. Integrated reference buffers and output amplifiers are also provided on-chip. The AD5024/AD5044/AD5064/AD5064-1 incorporate a power-on reset circuit that ensures the DAC output powers up to zero scale or midscale and remains there until a valid write takes place to the device. The AD5024/AD5044/ AD5064/AD5064-1 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. Total unadjusted error for the parts is <2 mV.
