Product Summary

The AD7237AARZ is a LC2MOS Dual 12-Bit DACPORT. Improvements include operation from 12V to 15V supplies, faster interface times and better reference variations with VDD. Additional features include faster settling times. The AD7237AARZ is a complete, dual, 12-bit, voltage output digital-to-analog converter with output amplifiers and Zener voltage reference on a monolithic CMOS chip. No external user trims are required to achieve full specified performance.
