DESCRIPTION
The Burr-Brown DAC7541A is a low cost 12-bit,
four-quadrant multiplying digital-to-analog converter.
Laser-trimmed thin-film resistors on a monolithic
CMOS circuit provide true 12-bit integral and differential linearity over the full specified temperature
range.
DAC7541A is a direct, improved pin-for-pin replacement for 7521, 7541, and 7541A industry standard
parts. In addition to a standard 18-pin plastic package,
the DAC7541A is also available in a surface-mount
plastic 18-pin SOIC.

DISCHARGE SENSITIVITY
PACKAGE INFORMATION
The DAC7541A is an ESD (electrostatic discharge) sensitive device. The digital control inputs have a special FET
structure, which turns on when the input exceeds the supply
by 18V, to minimize ESD damage. However, permanent
damage may occur on unconnected devices subject to high
energy electrostatic fields. When not in use, devices must be
stored in conductive foam or shunts. The protective foam
should be discharged to the destination socket before
devices are removed.

BURN-IN SCREENING
Burn-in screening is an option available for the models in the
Ordering Information table. Burn-in duration is 160 hours at
the indicated temperature (or equivalent combination of time
and temperature).
All units are tested after burn-in to ensure that grade specifications are met. To order burn-in, add “-BI” to the base
model number.
