LTC8043EN8#PBF

LTC8043EN8#PBF is a serial-input 12bit multiplying digital-to-analogue 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 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. Applications include process control and industrial automation, remote microprocessor-controlled systems, digitally controlled filters and power supplies, programmable gain amplifiers, and automatic test equipment.
