Automatic test equipment Digitally controlled calibration Servo controls Process control equipment GENERAL DESCRIPTION
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. 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 offsetting methods because it is not dependent on internal and external resistors with different temperature coefficients. Digital controls allow the user to load or read back data from any DAC, load any DAC, and transfer data to all DACs at one time.
