LTC8043 Serial 12-Bit Multiplying DAC in SO-8 Features s s s s s s s s DESCRIPTION The LTC®8043 is a serial-input 12-bit multiplying digitalto-analog converter (DAC). It is a superior pin patible 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 capacitance. 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. , LTC and LT are registered trademarks of Linear Technology Corporation.
