explained in INITIALIZATION TIME TO START CONVERSION. For continuous conversion, the initialization time is applicable only for

the first conversion.

(2)

Add 25µs for each additional channel enabled for conversion with CONV_AVG =000.

(3)

For conversion with CONV_AVG =101, each axis data is collected 32 times. If an additional channel is enabled with CONV_AVG =101,
