Instrumentation, Op Amps, Buffer Amps FAQ

How does the split reference configuration function?

REF1 and REF2 can be used together to form a voltage divider, allowing the output to be level-shifted to the center of an ADC's input range without requiring external components.

What is the purpose of the CLLO and CLHI pins?

These pins provide integrated output clamping. The voltage applied defines the lower and upper limits of the output swing, protecting downstream ADC inputs from overvoltage conditions.
