TCS3720 − Optical Characteristics

Note(s):

1. Dark ADC count refers to the full ALS count with ENAB_RES_BITS =0.

2. The gain ratios are calculated relative to the response with integration time = 13.9ms and ALS gain = 128x.

3. Representative result by lab characterization. An aperture with opening size of 1.2 x1.2mm is used in the setup that limits the device

FoV in the measurements.

4. The White LED is an InGaN light-emitting diode with integrated phosphor and the following characteristic: correlated color

temperature = 2700K.

5. Lux accuracy is an illuminance estimated using the red, green, blue, and clear channels and is not production tested.

6. ADC noise is representative result by lab characterization and calculated as the standard deviation of 1000 readings relative to full

scale.

7. The Blue LED is an InGaN light-emitting diode with the following characteristics: dominant wavelength λD = 465nm, spectral

halfwidth Δλ½ = 22nm.

8. The Red LED is an AlInGaP light-emitting diode with the following characteristics: dominant wavelength λD = 615nm, spectral

halfwidth Δλ½ = 15nm.

9. The Green LED is an InGaN light-emitting diode with the following characteristics: dominant wavelength λD = 525nm, spectral

halfwidth Δλ½ = 35nm.

Proximity Optical Characteristics (VDD18 = 1.8V, VDD3 = 3.0V, TA = 25°C unless otherwise noted)

Note(s):

1. At factory final test, proximity detector is redirected to ALS modulator for response measurement.
