TSL2772 − Absolute Maximum R atings

Note(s):

1. Parameter is ensured by design or characterization and is not tested.

2. Proximity noise is defined as one standard deviation of 600 samples.

3. Proximity noise typically increases as √PPULSE

4. Greater operating distances are achievable with appropriate optical system design considerations. See available ams OSRAM

application notes for additional information.

5. Maximum operating distance is dependent upon emitter and the reflective properties of the object’s surface.

6. Proximity noise test was done using Figure 10.
