Hi,

I got a diagram of a capacitance readout chip(attached).
Could anyone please tell me what do those triangles with different numbers inside them mean?

Thanks.

I think that the triangles represent amplifiers and the numbers represent the gain of the amplifier.

Yes I think JimB is right, they are amplifiers and/or op amps with gains listed.
You can look up the data sheet for that part and it may give you more info.
I just can't read Chinese.

Definitely amplifier symbols. But its not labelled if those values are in dB or simply a multiple of the input voltage
