The AD5683RARMZ is a low power 1-channel 16-bit buffered voltage out Digital-to-analog Converter (DAC) includes an enabled by default internal 2.5V reference, offering 2ppm/°C drift. This device operates from a single 2.7 to 5.5V supply and is guaranteed monotonic by design. The internal power-on reset circuit ensures that the DAC register is written to zero scale at power-up while the internal output buffer is configured in normal mode. The AD5683R contains a power-down mode that reduces the current consumption of the device to 2μA maximum at 5V and provides software selectable output loads while in power-down mode. It uses a versatile 3-wire serial interface that operates at clock rates of up to 50MHz.
