The AD5062， a member of ADI’s nanoDAC family， is a low power， single 16-bit unbuffered voltage-out DAC that operates from 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 a versatile 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 poweron reset circuit that ensures the DAC output powers up to zero scale or mid-scale and remains there until a valid write takes place to the device. The part contains a power-down feature that reduces the current consumption of the device to typically 300 nA at 5 V and provides software-selectable output loads while in power-down mode. The part is put into power-down mode over the serial interface. Total unadjusted error for the part is 《0.8 mV. This part exhibits very low glitch on power-up.
