GENERAL DESCRIPTION

They can be operated from a wide variety of supply and reference

voltages with supplies ranging from single +5 V to 15 V, and

references from +2.5 V to 10 V. Power dissipation is less than

330 mW with 15 V supplies and only 60 mW with a +5 V supply.

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.

For MIL-STD-883 applications, contact your local Analog

Devices, Inc. sales office for the DAC8412/DAC8413/883 data

sheet, which specifies operation over the −55°C to +125°C

temperature range. All 883 parts are also available on Standard

Military Drawings 5962-91 76401MXA through 76404M3A.

Output voltage swing is set by the two reference inputs V_REFH

and V_REFL. By setting the V_REFLinput to 0 V and V_REFHto a

positive voltage, the DAC provides a unipolar positive output

range. A similar configuration with V_REFHat 0 V and V_REFLat a

negative voltage provides a unipolar negative output range.

Bipolar outputs are configured by connecting both V_REFHand

_REFLto nonzero voltages. This method of setting output voltage

+125°C

range has advantages over other bipolar offsetting methods

because it is not dependent on internal and external resistors

with different temperature coefficients.

+25°C

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.
