ams TSL2672_EVM_EB Evaluation kit

The TSL2672 family of devices provides proximity detection when coupled with an external IR LED. The devices incorporate a constant-current LED sink driver to pulse the external IR LED and achieve very low average power consumption using the low power wait state with programmable wait time between proximity measurements. In addition, the devices are register-set and pin-compatible with the TSL2671 series and include a number of new and improved features, such as improved signal-to-noise and measurement accuracy. A proximity offset register allows compensation for optical system crosstalk between the IR LED and the sensor. To prevent false measurements, a proximity saturation bit indicates that the internal analog circuitry saturated. Interrupts have been enhanced with the addition of a sleep-after-interrupt feature that also allows for single-cycle operation.
