The AD5062, a member of ADI’s nanoDAC family, is a low power, single 16-bit unbuffered voltage-out DAC that operatesfrom a single 2.7 V to 5.5 V supply. The part offers a relative accuracy specification of ±1 LSB, and operation is guaranteed monotonic with a ±1 LSB DNL specification. The part uses aversatile 3-wire serial interface that operates at clock rates up to 30 MHz, and is compatible with standard SPI®, QSPI™, MICROWIRE™, and DSP interface standards. The reference for the AD5062 is supplied from an external VREF pin. A reference buffer is also provided on-chip. The part incorporates a power-on reset circuit that ensures the DAC output powers up to zero scale or mid-scale and remains there until a valid write takesplace to the device. The part contains a power-down featurethat reduces the current consumption of the device to typically300 nA at 5 V and provides software-selectable output loadswhile in power-down mode. The part is put into power-down mode over the serial interface. Total unadjusted error for thepart is <0.8 mV.
