DAC8412

Data Sheet FEATURES +5 V to ±15 V operation Unipolar or bipolar operation True voltage output Double-buffered inputs Reset to minimum (DAC8413) or center scale (DAC8412) Fast bus access time Readback APPLICATIONS Automatic test equipment Digitally controlled calibration Servo controls Process control equipment GENERAL DESCRIPTION The DAC8412/DAC8413 are quad, 12-bit voltage output DACs with readback capability. Built using a complementary BiCMOS process, these monolithic DACs offer the user very high package density. Output voltage swing is set by the two reference inputs VREFH and VREFL. By setting the VREFL input to 0 V and VREFH to a positive voltage, the DAC provides a unipolar positive output range. A similar configuration with VREFH at 0 V and VREFL at a negative voltage provides a unipolar negative output range. Bipolar outputs are configured by connecting both VREFH and VREFL to nonzero voltages. This method of setting output voltage range has advantages over other bipolar off...
