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.
Output voltage swing is set by the two reference inputs V
REFH
and V
REFL
. By setting the V
REFL
input to 0 V and V
REFH
to a
positive voltage, the DAC provides a unipolar positive output
range. A similar configuration with V
REFH
at 0 V and V
REFL
at a
negative voltage provides a unipolar negative output range.
Bipolar outputs are configured by connecting both V
REFH
and
V
REFL
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-lead plastic DIP,
28-lead ceramic DIP, 28-lead PLCC, and 28-lead LCC packages.
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.
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.
