GENERAL DESCRIPTION

The AD7570 is a monolithic CMOS 10-bit successive approximation A/D converter on a 120 by 135 mil chip, requiring only an external comparator, reference and passive clocking components. Ratiometric operation is inherent, since an extremely accurate multiplying DAC is used in the feedback loop.
