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 LMC6462/4. Large feedback resistors can react with small values of input capacitance due to
transducers, photodiodes, and circuits board parasitics to reduce phase margins.
