The LTC
®
7543/LTC8143 are serial-input 12-bit multiply-
ing digital-to-analog converters (DACs). They are superior
pin compatible replacements for the AD7543 and
DAC-8143. Improvements include better accuracy, better
stability over temperature and supply variations, lower
sensitivity to output amplifier offset, tighter timing speci-
fications and lower output capacitance.
An easy-to-use serial interface includes an asynchronous
CLEAR input for systems requiring initialization to a known
state. The LTC8143 has a serial data output to allow daisy-
chaining multiple DACs on a 3-wire interface bus.
These DACs are extremely versatile. They can be used for
2-quadrant and 4-quadrant multiplying, programmable
gain and single supply applications, such as noninverting
voltage output and biased or offset ground mode.
Parts are available in 16-pin PDIP and SO packages and
are specified over the extended industrial temperature
range, –40°C to 85°C.
