TSL2771 − Absolute Maximum Ratings

Figure 9:

Proximity Characteristics; VDD = 3 V, TA = 25°C, PEN = 1 (unless otherwise noted)

Note(s):

1. Proximity Operating Distance is dependent upon emitter properties and the reflective properties of the proximity surface. The

nominal value shown uses an IR emitter with a peak wavelength of 850nm and a 20º half angle. The proximity surface used is a 90%

reflective (white surface) 16

× 20-inch Kodak Gray Card. 60 mw/SR, 100 mA, 64 pulses, open view (no glass). Note: Greater distances

are achievable with appropriate system considerations.
