National Semiconductor ADC0801/ADC0802/ADC0803/ADC0804/ADC0805 8-Bit µP Compatible A/D Converters Datasheet
The ADC0801, ADC0802, ADC0803, ADC0804, and ADC0805 are CMOS 8-bit successive approximation A/D converters that use a differential potentiometric ladder structure. These devices are designed to operate with NSC800 and INS8080A derivative control buses, utilizing TRI-STATE output latches to directly drive the data bus without requiring additional interfacing logic.
