(1) CIN = Photodiode capacitance + PCB capacitance. Photodiode capacitance is 3.3 pF and estimated PCB capacitance is 0.7 pF. 
(2) Leakage currents from switches are not included in this measurement.
(3) CIN- refers to the capacitance at the inverting input of the amplifier. CIN- = CIN-(CM) + CDIFF + Switch capacitance on the amplifier inverting pin (ON capacitance of the closed switch + OFF capacitance for open switches).
