The DAC8412 and 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 volts and VREFH to a positive voltage, the DAC will provide a unipolar positive output range. A similar configuration with VREFH at 0 volts and VREFL at a negative voltage will provide 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. An active low RESET loads all DAC output registers to midscale for the DAC8412 and zero scale for the DAC8413. The DAC8412/DAC8413 are available in 28-pin plastic DIP, cerdip, PLCC and LCC packages. They can be operated from a wide variety of supply and reference voltages with supplies ranging from single +5 volt � 15 volts, and references from � 10 volts. Power dissipation is less than 330 mW with � 15 volt supplies and only 60 mW with a +5 volt supply. For MIL-STD-883 applications, contact your local ADI sales office for the DAC8412/DAC8413/883 data sheet which specifies operation over the to +125�C temperature range. All 883 parts are also available on Standard Military Drawings 5962-91-76401MXA through -76404M3A.
