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.
