Q
AD594/595 is monolithic thermocouple amplifiers
with cold junction compensation for J type thermocouple. Could it be used with
N type thermocouple?
A
AD594 and AD595 are Pretrimmed for Type J (AD594) or Type K (AD595)
Thermocouples. But they can be used with other type after calibration. Below is
an application note AN639 about the thermocouple signal conditioning, FYI.
