You have a digital system, which can presumably fix this in software, and
you want to go sticking _trimmers_ in your circuit?!?

The amps are well before the ADCs -- ADCs that sample at anything approaching
1Gsps have atrocious dynamic range compared to an analog signal processing
chain with a decent noise floor (e.g., 6 bits giving about 40dB dynamic range
vs. 80-100dB dynamic range back in the analog domain).
