1
LED inductance is negligible for these values. The effective slew rate slows with increased inductance.
2
Minimum LED period = (2 × AFE width) + 5 µs.
3
The maximum values in this specification are the internal ADC sampling rates in normal mode using the internal 32 kHz state machine clock. The I2C read rates in some
configurations may limit the output data rate.
4
This mode can induce additional noise and is not recommended unless necessary. The 1.8 V setting uses VDD, which contains greater amounts of differential voltage
noise with respect to the anode voltage.
5
This setting is not recommended for photodiodes because it causes a 1.3 V forward-bias of the photodiode.
