Note(s):

1. At shorter integration times and/or higher Prescale settings, the device will reach saturation of the analog section before the digital

count reaches the maximum 16-bit value. The worst-case (lowest) analog saturation value can be obtained using the formula: Analog

saturation = (fosc(min) ×Tint) ÷ Prescale, where Fosc(min) is the minimum oscillator frequency in Hz, and tint is the actual integration

time (internal, manually-timed, or sync-generated) in seconds.

2. Gain is controlled by the gain register (07h) described in the Register section.

3. Measurements taken when the Photodiode field value in the Photodiode Register (06h) is 00b and when the Prescaler field value

in the Gain Register (07h) is 000b.

4. The full scale ADC count value is slew-rate limited for short integration times and is limited by the 16-bit counter for long integration

times. The nominal transition between the two regions is tint = 65535/5000 = 13.1ms.
