Diode-connected configuration provides better settling time. Transistor-connected configuration provides better series
resistance cancellation.

RS (optional) should be < 1kΩ in most applications. Selection of RS depends on specific application; see Filtering
section.

CDIFF (optional) should be < 2200pF in most applications. Selection of CDIFF depends on specific application; see
Filtering section and Figure 9, Remote Temperature Error vs Differential Capacitance.
