AD570, Complete 8-Bit A-to-D Converter

The AD570 is a complete 8-bit A/D converter which requires no external components to provide the complete successiveapproximation analog-to-digital conversion function.

A block diagram of the AD570 is shown on last page.

Upon receipt of the CONVERT command, the internal 8-bit current output DAC is s
