Operational amplifiers (op amps, op-amps) are general-purpose, closed-loop devices that are used to implement linear functions. They compare two incoming signals and release a third signal that is an ...

Operational transconductance amplifiers (OTA) are devices that convert an input voltage to an output current. They are primarily voltage-to-current amplifiers. Unlike traditional operational ...

But to make that measurement you need an amplifier circuit designed for the thermocouple being used. Linear Technology LTC 1049 Low Power Zero-Drift Operational Amplifier with Internal Capacitors ...
