The DAC8412FPCZ is a quad 12-bit voltage output Digital-to-analog Converter (DAC) with read-back capability. Output voltage swing is set by the two reference inputs VREFH and VREFL. By setting the VREFL input to 0V and VREFH to a positive voltage, the DAC provides unipolar positive output range. A similar configuration with VREFH at 0V and VREFL at a negative voltage provides unipolar negative output range. Bipolar outputs are configured by connecting both VREFH and VREFL to non-zero 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 DAC at one time. An active low RESET load of DAC output registers to midscale for the DAC8412.
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.
