The ADC-85  is a self-contained,  high-performance, 12 Bit A/D converters manufactured with thick and thin-film hybrid technology. It uses successive approximation conversion technique to achieve a 12 Bit conversion in 8 microseconds. Five input voltage ranges are programmable by external pin connection. An internal buffer amplifier is also provided for applications in which 50 megohm input impedance is required. This converter is pin to pin compatible with the industry standards ADC84, ADC85 and ADC87.
