TYPICAL APPLICATIO S
8
Utilizing Negative LT1025 Drive to Accommodate Grounded Thermocouple*
*C1 AND C2 FILTER RIPPLE AND NOISE, BUT WILL LIMIT AC COMMON-MODE REJECTION
**USE LOWEST POSSIBLE SUPPLY VOLTAGE TO MINIMIZE INTERNAL TEMPERATURE RISE

IF NOT MATCHED. SUGGESTED VALUES ARE 0.001 F TO 0.1 F
FOR BEST ACCURACY, THERMOCOUPLE RESISTANCE SHOULD BE LESS THAN 100
