The AD5063， a member of ADI’s nanoDAC? family， is a low power， single 16-bit， unbuffered voltage-output DAC that operates from a single 2.7 V to 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 AD5063 comes with on-board resistors in a 10-lead MSOP， allowing bipolar signals to be generated with an output amplifier. The part uses a versatile 3-wire serial interface that operates at clock rates up to 30 MHz and that is compatible with standard SPI?， QSPI?， MICROWIRE?， and DSP interface standards. The reference for the AD5063 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 midscale and remains there until a valid write to the device takes place. 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 via the serial interface. Total unadjusted error for the part is 《1 mV. This part exhibits very low glitch on power-up
