CY8CMBR3102-SX1I

CY8CMBR3102-SX1I is a 2-button capacitive touch proximity sensor. It features an advanced analogue sensing channel and the capacitive sigma delta PLUS sensing algorithm, which delivers a signal-to-noise ratio of greater than 100:1 to ensure touch accuracy even in extremely noisy environments. The wake-on-approach feature wakes the devices from a low-power state to active mode on a proximity event. The device also features a driven shield, which enhances the proximity sensing range in the presence of metal objects. It detects changes in capacitance to determine the presence of a touch or proximity to conductive objects. The capacitive sensor can be a capacitive button that replaces the traditional mechanical buttons, a capacitive slider that replaces mechanical knobs or a proximity sensor that replaces an infrared sensor in a user interface solution.
