A Thermocouple is a terrific way to measure temperature. The effects of temperature change on dissimilar metals produces a measurable voltage. 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 While researching “Zero Drift

A great tech not on OP Amps driving capacitance. http://www.analog.com/library/analogDialogue/archives/31-2/appleng.html Q. How does capacitive loading affect op amp performance? A. To put it simply, it can turn your amplifier into an oscillator. Here's how: Op amps have an inherent output resistance, Ro, which, in conjunction with a capacitive load, forms an
