AD571: 10-Bit, A/D Converter, Complete with Reference and Clock

The AD571 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 us.

Operating on supplies of +5 V to +15 V and -15 V, the AD571 will accepts analog inputs of 0 V to +10 V unipolar of ±5 V bipolar, externally selectable. When the BLANK and CONVERT input is driven low, the three state outputs will be open and a conversion will commence. Upon completion of the the DATA READY line goes low and the data pears at the output. Pulling the BLANK and CONVERT input high blanks the outputs and readies the device for the next version. The AD571 executes a true 10-bit conversion with no missing codes in 40 us maximum.

The AD571 is available in two version for the 0°C to +70°C temperature range, the AD571J and K. The AD571S guarantees 10-bit accuracy and no missing codes from -55°C to +125°C.
