ADC0805 8-Bit uP Compatible A/D Converters

The ADC0801, ADC0802, ADC0803, ADC0804 and ADC0805 are CMOS 8-bit successive approximation A/D converters that use a differential potentiometric ladder * similar to the 256R products. These converters are designed to allow operation with the NSC800 and INS8080A derivative control bus with TR.

ADC0805 Features
