Amp Input Instrumentation Range

Click For Summary

To calculate the common-mode input range of an instrumentation amplifier with op-amps biased from +15V to -15V, it's essential to refer to the specific amplifier's datasheet for detailed specifications. The common-mode input range is influenced by the op-amps' ability to swing rail to rail, which allows for maximum input voltage levels. A schematic of the circuit may be necessary for a more accurate analysis and understanding of the configuration. Proper calculations depend on the amplifier's characteristics and the specific application requirements. Understanding these factors is crucial for effective design and implementation.

Can anyone tell me how to calculate the common-mode input range of an instrumentation amplifier with all op-amps biased from +15V to -15V assuming all op-amps can swing rail to rail.

Thanks.

you should look at the specs on the datasheet for your amp

Looks like homework. And we'd need a schematic.

Thread 'I thought it was only Amazon that sold unsafe junk'

I grabbed an under cabinet LED light today at a big box store. Nothing special. 18 inches in length and made to plug several lights together. Here is a pic of the power cord: The drawing on the box led me to believe that it would accept a standard IEC cord which surprised me. But it's a variation of it. I didn't try it, but I would assume you could plug a standard IEC cord into this and have a double male cord AKA suicide cord. And to boot, it's likely going to reverse the hot and...
