GENERAL DESCRIPTION
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®, QSPI™, MICROWIRE™, 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.
