AD5725ARSZ-500RL7 (ANALOG DEVICES)

The AD5725ARSZ-500RL7 is a quad 12-bit parallel input voltage output Digital-to-analog Converter that offers guaranteed monotonicity, integral nonlinearity (INL) of ±0.5LSB maximum and 10µs maximum settling time. Output voltage swing is set by two reference inputs VREFP and VREFN. By setting the VREFN input to 0V and the VREFP to a positive voltage, the DAC provides unipolar positive output range. A similar configuration with VREFP at 0V and VREFN at a negative voltage provides unipolar negative output range. Bipolar outputs are configured by connecting both VREFP and VREFN to non-zero voltages. This method of setting output voltage ranges has advantages over the bipolar offsetting methods because it is not dependent on internal and external resistors with different temperature coefficients. Digital controls allow the user to load or read back data from any DAC, load any DAC and transfer data to DAC at one time.
