GENERAL DESCRIPTION

The AD5025/AD5045/AD5065 are low power, dual 12-/14-/16-bit buffered voltage output nanoDAC® DACs offering relative accuracy specifications of ±1 LSB INL with individual reference pins, and can operate from a single 4.5 V to 5.5 V supply. The AD5025/ AD5045/AD5065 also offer a differential accuracy specification of ±1 LSB. 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.
