Closed-loop servo control, process control Automotive test and measurement Programmable logic controllers GENERAL DESCRIPTION The AD5725 is a quad, 12-bit, parallel input, voltage output Digital controls allow the user to load or read back data from digital-to-analog converter that offers guaranteed monotonicity, any DAC, load any DAC, and transfer data to all DACs at integral nonlinearity (INL) of 0.5 LSB maximum and 10 s one time. maximum settling time. The AD5725 is available in a 28-lead SSOP package. It can be Output voltage swing is set by two reference inputs, V and operated from a wide variety of supply and reference voltages, REFP V . By setting the V input to 0 V and the V to a with supplies ranging from single +5 V to 15 V, and references REFN REFN REFP positive voltage, the DAC provides a unipolar positive output from +2.5 V to 10 V. Power dissipation is less than 270 mW range. A similar configuration with VREFP at 0 V and VREFN at a with 15 V supplies and only 40 mW with a +5 V supply. negative voltage provides a unipolar negative output range. Operation is specified over the temperature range of 40C Bipolar outputs are configured by connecting both VREFP and to +85C. 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. iCMOS Process Technology For analog systems designers within industrial/instrumentation equipment OEMs who need high performance ICs at higher-voltage levels, iCMOS is a technology platform that enables the development of analog ICs capable of 30 V and operating at 15 V supplies while allowing dramatic reductions in power consumption and package size, and increased ac and dc performance.
