AD5726

Quad, 12-Bit, Serial Input, Unipolar/Bipolar, Voltage Output DAC AD5726 FEATURES +5 V to ±15 V operation Unipolar or bipolar operation ±1 LSB maximum INL error, ±1 LSB maximum DNL error Guaranteed monotonic over temperature Double-buffered inputs Simultaneous updating via LDAC Asynchronous CLR to zero scale/midscale Operating temperature range: −40°C to +125°C iCMOS® process technology1 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. The AD5726 uses a serial interface that operates at clock rates up to 30 MHz and is compatible with DSP and microcontroller interface standards. Double buffering allows simultaneous updating of all DACs. The asynchronous CLR function clears all DAC registers to a user-selectable, zero-scale or midscale output. The AD5726 is available in 16-lead SSOP and 16-lead SOIC packages. It can be operated from a wide variety of supply and reference voltages with supplies ranging from single +5 V to ±15 V, and references ranging from +2.5 V to ±10 V. Power dissipation is less than 240 mW with ±15 V supplies and only 30 mW with a +5 V supply. Operation is specified over the temperature range of −40°C to +125°C. Table 1.
