Recommended Operating Conditions at 25 °C
Table 10 lists the recommended operating conditions common to all three modules. Table 11 lists the
recommended operating conditions particular to each of the three LED light sources.
Note
1. The maximum clock speed is limited by the modules light source power, due to the low light power
associated with LED’s.
The minimum clock speed is determined by the longest tolerable integration time. Because of the
leakage current build up, the integration time is recommended to be no greater than 10 ms.
