Hi again, I know the basics of electronics and I'm working with a ADXL103 analog accelerometer. I'm using it to drive two 10k trimmers as voltage dividers to sense the change in voltage when the angle of the ADXL103 changes in respect to the ground.

Essentially an angle gauge.

However when I put a load on this poor little IC the voltage of the ADXL103 drops to almost nothing.

So I need to amplify the signal but keep the analog logic in it to sense when it's at certain angles.

Any recommendations?

 

Hello,

When you look at the block-diagram of the ADXL103, the output has a 32K resistor as part of the output filter:

You can use an opamp as buffer:

I love this forum!

Worked great!

Quick and accurate responses, thanks!
