Product Summary

The AD7248AARZ is a complete, 12-bit, voltage output, digital-to-analog converter with output amplifier and Zener voltage reference on a monolithic CMOS chip. Improvements include operation from 12 V to 15 V supplies, a ±1/2 LSB linearity grade, faster interface times and better full scale and reference variations with VDD. Additional features of the AD7248AARZ include extended temperature range operation for commercial and industrial grades. No external user trims are required to achieve full specified performance.
