GENERAL DESCRIPTION

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 V
and V

. By setting the V

REFL

input to 0 V and V

REFL

positive voltage, the DAC will provide a unipolar positive output
range. A similar configuration with V

at 0 V and V

REFH

a negative voltage will provide a unipolar negative output range.
Bipolar outputs are configured by connecting both V

to nonzero voltages. This method of setting output voltage

V

REFL

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,
PLCC and 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 ADI 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.

CAUTION

1. Stresses above those listed under Absolute Maximum Ratings may cause permanent damage to the

device. This is a stress rating only; functional operation at or above this specification is not implied.
Exposure to the above maximum rating conditions for extended periods may affect
device reliability.

WARNING!

2. Digital inputs and outputs are protected, however, permanent damage may occur on unprotected units

from high-energy electrostatic fields. Keep units in conductive foam or packaging at all times until
ready to use. Use proper antistatic handling procedures.

3. Remove power before inserting or removing units from their sockets.

4. Analog outputs are protected from short circuit to ground or either supply.
