DESCRIPTION
The LTC
to-analog converter (DAC).
Laser-trimmed thin-film resistors provide excellent abso-
lute accuracy. Precision matched resistors and CMOS
circuitry result in remarkable stability with temperature
and supply variations.
The LTC7541A is a superior pin compatible replacement
for the industry standard AD7541A/AD7541. Improve-
ments include better typical accuracy and stability and
reduced sensitivity to output amplifier offset. The LTC7541A
is also very resistant to latch-up.
In addition to 2-quadrant and 4-quadrant multiplying
configurations, the LTC7541A performs well in digitally
programmable gain and noninverting voltage output ap-
plications. Low cost, improved performance and versatil-
ity make the LTC7541A the best choice for many new
designs and for upgrading existing systems. Parts are
available in 18-pin PDIP and 18-pin SO Wide packages.
