DESCRIPTION…
The SP7800A is a complete 12-bit sampling A/D converter using state–of–the–art CMOS structures.
It contains a complete 12–bit successive approximation A/D converter with internal sample/hold,
reference, clock, digital interface for microprocessor control, and three–state output drivers. AC and
DC performance are completely specified. Two grades based on linearity and dynamic performance
are available to provide the optimum price/performance fit in a wide range of applications.
