Maxim MAX5217 16-bit Digital-to-Analog-Converter

Maxim Integrated MAX5217 16-bit digital-to-analog converter (DAC) is a single-channel, low-powered, buffered voltage-output device that uses a precision external reference applied through the high resistance input for rail-to-rail operation and low system power consumption. MAX5217 uses a precision external reference applied through the high resistance input for rail-to-rail operation and low system power consumption. Maxim MAX5217 accepts a wide 2.7V to 5.5V supply voltage range. The DAC output is buffered resulting in a low supply current of 80µA (max) and a low offset error of ±0.25mV. Power consumption is extremely low to accommodate most low-power and low-voltage applications. It also has an I²C-compatible, 2-wire serial interface that operates at clock rates up to 400kHz. On power-up, MAX5217 resets the DAC output to zero, providing additional safety for applications that drive valves or other transducers that need to be off on power-up. MAX5217 evaluation kit demonstrates MAX5217 and provides controls to change the DAC output and power operations.
