open view (no glass) above the module.
Notes:
1. This parameter is ensured by design and characterization and is not 100% tested. 8 pulses are the recommended driving conditions. For other
driving conditions, contact Avago Field Sales.
2. Value may be as much as 1.36μs longer than specied.
3. Value is factory-adjusted to meet the Proximity count specication. Considerable variation (relative to the typical value) is possible after adjustment.
LED BOOST increases current setting (as dened by LDRIVE or GLDRIVE). For example, if LDRIVE = 0 and LED BOOST = 100%, LDR current is 100mA.
4. Proximity oset value varies with power supply characteristics and noise.
5. ILEDA is factory calibrated to achieve this specication. Oset and crosstalk directly sum with this value and is system dependent.
6. No glass or aperture above the module. Tested value is the average of 5 consecutive readings.

Notes:
1. Each U/D or R/L pair requires a conversion time of 696.6ms. For all four directions the conversion requires twice as much time.
2. This parameter ensured by design and characterization and is not 100% tested. 8 pulses are the recommended driving conditions. For other
driving conditions, contact Avago Field Sales.
3. Value may be as much as 1.36ms longer than specied.
4. Value is factory-adjusted to meet the Gesture count specication. Considerable variation (relative to the typical value) is possible after adjustment.
5. When operating at these LED drive conditions, it is recommended to separate the VDD and VLEDA supplies.
6. Gesture oset value varies with power supply characteristics and noise.
7. ILEDA is factory calibrated to achieve this specication. Oset and crosstalk directly sum with this value and is system dependent.
8. No glass or aperture above the module. Tested value is the average of 5 consecutive readings.
