The measurement time tMEASURE is influenced by many parameters like modulator clock, filter

order and decimation filter setting. Table 9 provides example register configurations with the

resulting measurement times tMEASURE depending on the modulator clock settings. In case

additional information about different register settings are required please do consult your local

ams OSRAM support team for assistance.
