Hi,

I got a diagram of a capacitance readout chip like shown below.

Could anyone please tell me what do those triangles with different numbers inside them mean?

Thanks.

My guess is that they signify gain stages with the gain as indicated by the number.

what's wrong with a gain of -1? it's just an inverting amplifier.

But like I said, it's just an educated guess.

I second your educated guess with my educated guess. I was going to post that, but I was not certain.
