The LTC

to-analog converter (DAC). It is a superior pin compatible

replacement for the DAC-8043. Improvements include

better accuracy, better stability over temperature and

supply variations, lower sensitivity to output amplifier

offset, tighter timing specifications and lower output ca-

pacitance.

An easy-to-use 3-wire serial interface is well-suited to

remote or isolated applications

The LTC8043 is extremely versatile. It can be used for

2-quadrant and 4-quadrant multiplying, programmable

gain and single supply applications, such as noninverting

voltage output mode.

Parts are available in 8-pin SO and PDIP packages and are

specified over the extended industrial temperature range,

–40

°C to 85°C.
