ADC1001 10-Bit uP Compatible A/D Converter

The ADC1001 is a CMOS, 10-bit successive approximation A/D converter. The 20-pin ADC1001 is pin compatible with the ADC0801 8-bit A/D family. The 10-bit data word is read in two 8-bit bytes, formatted left justified and high byte first. The six least significant bits of the second byte are set to ze.
