General Description:

SC05A is a capacitive sensor with auto sensitivity calibration, and capable of detecting touch on up to 5

touch-pads. It allows touch pad to project independent sense fields through any dielectric such as glass or

plastic. This capability can lead to entirely new product concepts, adding high value to product designs.

Features:

◇ 5 completely independent touch sensing keys.

◇ 100% auto-cal for life - no adjustments required.

◇ Fully debounced results.

◇ Multi interface – I2C serial interface / Parallel outputs.

◇ All keys share one sensitivity capacitance.

◇ Different Length of touch-pads wires will not lead to different sensitivity.

◇ 2.5V ~ 6.0V single supply operation.

◇ RoHS compliant SOP16 package.

Application:

◇ Mechanical switch replacement.

◇ Home appliances (TV, Monitor keypads).

◇ Human interface for Toys & interactive games.

◇ Door key-lock matrix application.

◇ Switch for light controls.

◇ Sealed control panels, keypads.
