GENERAL DESCRIPTION

The AD5726 is a quad, 12-bit, serial input, voltage output digital-to-analog converter (DAC) fabricated on Analog Devices, Inc., iCMOS® process technology1 that offers guaranteed monotonicity and integral nonlinearity (INL) of ±1 LSB maximum.

Output voltage swing is set by two reference inputs, VREFP and VREFN. The DAC offers a unipolar positive output range when the VREFN input is set to 0 V and the VREFP input is set to a positive voltage. A similar configuration with VREFP at 0 V and VREFN at a negative voltage provides a unipolar negative output range.

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 offsetting methods because it is not dependent on internal and external resistors with different temperature coefficients.
