LTC2983 Datasheet mistake

Question

Figure 12 (3-Wire RTD example) of the LTC2983 datasheet shows a capacitor on Ch6 even though it also shows that this channel should be grounded. The capacitor is pointless but I want to be sure there was not some other mistake when I design my board to read 3Wire RTDs around this example. 
 Thanks,

Hi keithwm422 ,

Sorry for the confusion. As it can be seen in the Figure 11 of the datasheet, the ground at Ch6 is optional (should be left floating when sharing the Rsense). Therefore you should connect Ch6 either to ground or the capacitor, but not to both at the same time.

I hope this helps.

Regards,
Karlo
