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 differ-
ential linearity over the full specified temperature
range.
DAC7541A is a direct, improved pin-for-pin replace-
ment 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.
