GENERAL DESCRIPTION
The AD5066 is a low power, 16-bit quad-channel, unbuffered voltage output nanoDAC® offering relative accuracy specifications of ±1 LSB INL with individual reference pins and can operate from a single 2.7 V to 5.5 V supply. The AD5066 also offers a differential accuracy specification of ±1 LSB DNL. Reference buffers are also provided on-chip. The part uses 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 most DSP interface standards.
