Notes
1. Measurement performed with Ci = 0.5 pF comprising 0.4 pF (photodiode) and 0.1 pF (allowed for PCB layout).
2. PSRR is defined as the ratio of change in input current (∆Ii) corresponding to change in supply voltage (∆VCC):
PSRR = ∆-----∆V----IC--i--C-
For example, a 4 mV disturbance on VCC at 10 MHz will typically add an extra 120 nA to Ii (photodiode output
current). The value of the external capacitor connected between pads DREF and GND has a significant effect on the
value of PSRR. The specification is valid with an external capacitor of 1 nF.
