*CP = SUM OF PHOTODIODE CAPACITANCE, PARASITIC LAYOUT

CAPACITANCE AND LT1797 INPUT CAPACITANCE 10pF.

C3

1000pF

TRANSIMPEDANCE GAIN: AZ = 10MΩ.

R6, C3 LIMIT THE NOISE BANDWIDTH TO 500kHz.

OUTPUT NOISE 1.8mVRMS.

R1, CP AND LT1797 GBW SET UPPER LIMIT ON BANDWIDTH.

R4, C2 SET LOWER 1.6kHz LIMIT ON GAIN OF 101.
