AD5725ARSZ-1500RL7

AD5725ARSZ-1500RL7 is a quad, 12-bit, parallel input, voltage output digital-to-analogue converter. The 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 a unipolar positive output range. A similar configuration with VREFP at 0V and VREFN at a negative voltage provides a unipolar negative output range. The bipolar outputs are configured by connecting both VREFP and VREFN to nonzero voltages. This method of setting output voltage ranges has advantages over the bipolar off-setting methods because it is not dependent on internal and external resistors with different temperature coefficients. Digital controls allow user to load or read back data from any DAC, load any DAC, and transfer data to all DACs at one time. It is used in applications such as industrial automation, closed-loop servo control, process control, automotive test and measurement, and programmable logic controllers.
