AD7224 Overview
The AD7224 is a precision 8-bit voltage-output, digital-toanalog converter, with output amplifier and double buffered interface logic on a monolithic CMOS chip. No external trims are required to achieve full specified performance for the part. The double buffered interface logic consists of two 8-bit registers–an input register and a DAC register. Only the data held in the DAC registers determines the analog output of the converter. The double buffering allows simultaneous update in a system containing multiple AD7224s. Both registers may be made transparent under control of three external l
