Buffered Mode
When used in buffered mode, the buffers isolate the
inputs from the sampling capacitors. The sampling-
related gain error is dramatically reduced since only a
small dynamic load is present from the chopper. The
multiplexer exhibits an input leakage current of 0.5nA
(typ). With high-source resistances, this leakage cur-
rent may result in a large DC offset error.
