Functional Description

Signal on the analog signal input pin ANI is input into the comparators on the rising edge of the CLK input signal. This signal is

compared with the voltage divided by resistors and digitized. This digitized signal is coded by the encoder logic and output on the

output data is linearly related to the input voltage as shown in the table below.
