LTC8043 Serial 12-Bit Multiplying DAC in SO-8 FEATURES DESCRIPTION n Improved Direct Replacement for DAC-8043 and The LTC 8043 is a serial-input 12-bit multiplying digital- MAX543 to-analog converter (DAC). It is a superior pin compatible n SO-8 Package replacement for the DAC-8043. Improvements include n DNL and INL Over Temperature: 0.5LSB better accuracy, better stability over temperature and n Easy, Fast and Flexible Serial Interface supply variations, lower sensitivity to output amplifier n 1LSB Maximum Gain Error offset, tighter timing specifications and lower output ca- n 4-Quadrant Multiplication pacitance. n Low Power Consumption An easy-to-use 3-wire serial interface is well-suited to n Low Cost remote or isolated applications U The LTC8043 is extremely versatile. It can be used for APPLICATIONS 2-quadrant and 4-quadrant multiplying, programmable gain and single supply applications, such as noninverting n Process Control and Industrial Automation voltage output mode. n Remote Microprocessor-Controlled Systems n Digitally Controlled Filters and Power Supplies Parts are available in 8-pin SO and PDIP packages and are n Programmable Gain Amplifiers specified over the extended industrial temperature range, n Automatic Test Equipment 40C to 85C. , LTC and LT are registered trademarks of Linear Technology Corporation.
