Can ΔΣ A/D converter be used as single end input?

Latest Updated:04/07/2011


For the ΔΣ A/D converter, when grounding (connecting to GND) the N side of a differential input pin, can it be used as single-end input?


No, the result will not be the same as single-end input even if the N-side of the differential input pin is connected to GND and a single-end signal is input to the P-side.
Theoretically, when an off-set cancel value is input to an N-side pin, operation will be similar to single-end.
However, this is not guaranteed.
Please carefully evaluate for your system before using.
