Hi,
I am building the circuit for LT1050, datasheet page 9
I tried the exact circuit (Excpt the C .068 uF, I put as .01uF), while ThermoCouple Type K is not under any heating, but I got the output signal at LT1050-pin6 as 2.7v, I was expecting getting like .3 v as only room tempreture degree. according to my understanding 2.7 V means 270 C.

Type KCoofecient 0.0000406
Rf (Ohm) 255000
Ri (Ohm) 1000
Gain 255
Vout 0.0010759

My analysis for Circuit is according to Datasheet, but not matched with my trial. Appreciate your help please.

Regards,
Hytham Soliman

Welcome to AAC!

A thread belongs to the OP (original poster). Trying to take over someone elses thread is called hijacking, which is not allowed at All About Circuits. I have therefore given you a thread of your very own.

This was split from Thermocouple circuit.

You have also practiced the arcane art of necromancy, as this thread is well over 4 years old. The OP of that thread is long gone, probably never to return.
