Quad, 12-Bit, Serial Input,
Unipolar/Bipolar, Voltage Output DAC
AD5726 Data Sheet 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. 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
Asynchronous CLR to zero scale/midscale
Operating temperature range: −40°C to +125°C
iCMOS process technology 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. The asynchronous CLR function clears all DAC
registers to a user-selectable zero-scale or midscale output. APPLICATIONS
