Update error calculations doc with AC errors too - 5 kHz amplitude accuracy sources include:

Rcs tolerance
loop gain @ target freq.
DAC filter initial tolerance/stability (atten./phase shift @ 5k and how much that changes w/component tol. + drift)
CMRR of INA828 (85 dB typ.)
PSRR of INA828 w/meas. power rail swings (90 dB typ.) [this one will be small]
