ZN427E8 MICROPROCESSOR COMPATIBLE 8-BIT SUCCESSIVE APPROXIMATION A-D CONVERTER

ZN427E8 / ZN427J8 MICROPROCESSOR COMPATIBLE 8-BIT SUCCESSIVE APPROXIMATION A-D CONVERTER The ZN427 is an 8-bit successive approximation converter with three-state outputs to permit easy interfacing to a common data bus. The IC contains a voltage switching DAC, a fast comparator, successive approximation logic and a 2.56V precision bandgap reference, the use of which is pin optional to retain flexibility. An external fixed or varying reference may therefore be substituted, thus allowing ratiomet.
