Leakage at the RSET Pin
Leakage currents at the RSET pin, such as those generated from a
moist environment or printed circuit board contamination, can
have an adverse effect on the programmed setpoint temperature
of the AD22105. Depending on its source, leakage current can
flow into or out of the RSET pin. Consequently, the actual
setpoint temperature could be higher or lower than the intended
setpoint temperature by about 1
°C for each 75 nA of leakage.
With a 5 V power supply, an isolation resistance of 100 M
would create 50 nA of leakage current giving a setpoint
temperature error of about 0.7
°C (the R
SET pin is near ground
potential). A guard ring can be placed around the RSET node to
protect against leakage from the power supply pin (as shown in
Figure 13).
