The thermocouple temperature/frequency converter circuit

Published:2011/6/3 1:20:00 Author:Seven | Keyword: thermocouple, temperature/frequency converter | From:SeekIC

The output pulse of I3 drives the DIN-pin of LTCI146, and GNDI is connected with I3. The output of DOUT and TIL are compatible with signals. The maximum consumption current of the circuit is 460μA, and it is allowed to use the 9v power supply. LT1025 is the thermocouple cool pole compensator, LTC1049 is a low-power computing amplifier which contains capacitors, and LTC1146 is an integrated signal separating circuit.
