The AD5063, a member of ADI’s nano
DAC® 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.
