LTC7541A

Improved

Industry Standard CMOS

12-Bit Multiplying DAC

FEATURES

DESCRIPTION

The LTC

7541A is a 12-bit resolution multiplying digital-

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.
