The ideal place to connect the LM88’s GND pin is as

close as possible to the processor GND associated with

the sense diode.

9.

Leakage current between D+ and GND should be kept

to a minimum. One nano-ampere of leakage can cause

as much as 1˚C of error in the diode temperature read-

ing. Keeping the printed circuit board as clean as pos-

sible will minimize leakage current.
