R/W

[7:0]

readout__averaging_sample_period: The internal readout averaging sample period can be

adjusted from 0 to 255. Increasing the sampling period decreases noise but also reduces the

effective max convergence time and increases power consumption:



Effective max convergence time = max convergence time - readout averaging period (see

Section 2.6: Range timing). Each unit sample period corresponds to around 64.5 µs additional

processing time. The recommended setting is 48 which equates to around 4.3 ms.
