The example values in this circuit result in a gain of 1. Is this not what you want?
There are integrated difference amplifiers like the INA154/INA132/INA152 or instrumentation amplifiers like the INA823/INA826/INA188 with more accurate resistors.
Hi Karthik,
One doubt, if C4=28pf=C9, the U1 and U2 output should be same ryt. Then U3 output should be zero. Please correct if wrong.
My concern is that if the amplifier is having higher bias currents, it will result only as a low frequency offset which…
Hi Saeed,
There are many options to design the thermistor circuit, and convert the voltage to 4-20mA current loop. I need to have clear direction how you want to proceed.
Your thermistor application is operating such a wide temperature range from ~700kΩ…
