COMPENSATING FOR INPUT CAPACITANCE
It is quite common to use large values of feedback resistance with amplifiers that have ultra-low input current,
like the LMC6482. Large feedback resistors can react with small values of input capacitance due to transducers,
photo diodes, and circuits board parasitics to reduce phase margins.
