ADC1001

ADC1001 10-Bit µP Compatible A/D Converter June 1999 ADC1001 10-Bit µP Compatible A/D Converter General Description 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 zero, as is proper for a 16-bit word. Differential inputs provide low frequency input common mode rejection and allow offsetting the analog range of the converter. In addition, the reference input can be adjusted enabling the conversion of reduced analog ranges with 10-bit resolution.
