Process control equipment GENERAL DESCRIPTION
The DAC8412/DAC8413 are quad, 12-bit voltage output They can be operated from a wide variety of supply and reference DACs with readback capability. Built using a complementary voltages with supplies ranging from single +5 V to ±15 V, and BiCMOS process, these monolithic DACs offer the user very references from +2.5 V to ±10 V. Power dissipation is less than high package density. 330 mW with ±15 V supplies and only 60 mW with a +5 V supply. Output voltage swing is set by the two reference inputs VREFH For MIL-STD-883 applications, contact your local Analog and VREFL. By setting the VREFL input to 0 V and VREFH to a Devices, Inc. sales office for the DAC8412/DAC8413/883 data positive voltage, the DAC provides a unipolar positive output sheet, which specifies operation over the −55°C to +125°C range. A similar configuration with VREFH at 0 V and VREFL at a temperature range. Al 883 parts are also available on Standard negative voltage provides a unipolar negative output range. Military Drawings 5962-91 76401MXA through 76404M3A. Bipolar outputs are configured by connecting both VREFH and

VREFL to nonzero voltages. This method of setting output voltage
