Product Summary

The AD571JD is an 10-bit successive approximation A/D converter consisting of a DAC, voltage reference, clock, comparator, successive approximation register and output buffers—all fabricated on a single chip. No external components are required to perform a full accuracy 10-bit conversion in 40 ms. When the AD571JD input is driven low, the three-state outputs will be open and a conversion will commence. Upon completion of the conversion, the DATA READY line goes low and the data appears at the output. Pulling the BLANK and CONVERT input high blanks the outputs and readies the device for the next conversion. The AD571JD executes a true 10-bit conversion with no missing codes in 40 ms maximum.
