LTC8143 Improved Industry Standard Serial 12-Bit Multiplying DACs

The LTC7543/LTC8143 are serial-input 12-bit multiplying 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 specifications 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 out put 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
