Amp Input Instrumentation Range

AI Thread 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 'Weird near-field phenomenon I get in my EM simulation'

I recently made a basic simulation of wire antennas and I am not sure if the near field in my simulation is modeled correctly. One of the things that worry me is the fact that sometimes I see in my simulation "movements" in the near field that seems to be faster than the speed of wave propagation I defined (the speed of light in the simulation). Specifically I see "nodes" of low amplitude in the E field that are quickly "emitted" from the antenna and then slow down as they approach the far...

Thread 'EMF (Electromagnetic Field) & EHS (Electromagnetic Hyper Sensitivity)'

Hello dear reader, a brief introduction: Some 4 years ago someone started developing health related issues, apparently due to exposure to RF & ELF related frequencies and/or fields (Magnetic). This is currently becoming known as EHS. (Electromagnetic hypersensitivity is a claimed sensitivity to electromagnetic fields, to which adverse symptoms are attributed.) She experiences a deep burning sensation throughout her entire body, leaving her in pain and exhausted after a pulse has occurred...
