The AD5066 is a low power, 16-bit quad-channel, unbuffered voltage-out DAC offering relative accuracy specs of 1LSB INL with individual reference pin and can operate from a single 2.7V to 5.5V. The AD5066 parts also offer a differential accuracy specification of 1 LSB. Reference buffers are also provided on-chip. The parts use a versatile 3-wire, low power Schmitt trigger serial interface that operates at clock rates up to 50 MHz and is compatible with standard SPI, QSPITM, MICROWIRETM, and DSP interface standards. The AD5066 incorporates a power-on reset circuit that ensures the DAC output powers up zero scale or midscale and remains there until a valid write takes place to the device. The AD5066 contain a power-down feature that reduces the current consumption of the device to typically 330 nA at 5 V and provides software selectable output loads while in power-down mode. The part can be placed into power-down mode over the serial interface. Total unadjusted error for the part is <0.8 mV. Both parts exhibit very low glitch on power-up.
