TSL2561 − Electrical Characteristics

6. Low gain mode has 16× lower gain than high gain mode: (1/16 = 0.0625).

7. The sensor Lux is calculated using the empirical formula shown in Calculating Lux of this data sheet based on measured Ch0 and

Ch1 ADC count values for the light source specified. Actual Lux is obtained with a commercial luxmeter. The range of the (sensor

Lux) / (actual Lux) ratio is estimated based on the variation of the 640nm and 940nm optical parameters. Devices are not 100% tested

with fluorescent or incandescent light sources.
