Overview
The LTC8043ES8#PBF is a serial-input 12-bit multiplying digital-to-analog converter (DAC) produced by Analog Devices Inc. It is designed as a superior pin-compatible replacement for the DAC-8043 and MAX543. This DAC offers improved accuracy, stability over temperature and supply variations, and lower sensitivity to output amplifier offset. It features a 3-wire serial interface, making it well-suited for remote or isolated applications. The LTC8043 is available in 8-pin SOIC and PDIP packages and is specified over the extended industrial temperature range of –40°C to 85°C.
