temperature range, otherwise specificatons are at T
Note 1: Absolute Maximum Ratings are those values beyond which the
life of a device may be impaired.
Note 2: Divider accuracy is measured by applying a 10.000V signal to the
output divider and measuring the individual outputs.
Note 3: Regulation does not include the effects of self-heating. See
“Internal Temperature Rise” in Application Guide. Load regulation is

Consult LTC Marketing for parts specified with wider operating temperature ranges.
Note 4: To calculate total temperature error at individual thermocouple
outputs, add 10mV/ C output error to the resistor divider error. Total error
for type K output at 25 C with an LT1025A is 0.5 C plus (0.4 V/ C)(25 C)/
(40.6 V/ C) = 0.5 C + 0.25 C = 0.75 C.
Note 5: Temperature error is defined as the deviation from the following
formula: V
term is a built-in nonlinearity designed to help compensate the nonlinearity
of the cold junction . This “bow” is 0.34 C for a 25 C temperature change.
