Capacitive touch controllers

29 January 2014 Analogue, Mixed Signal, LSI

Microchip has unveiled a new family of capacitive touch controllers in the form of the CAP12XX range. These turnkey controllers expand the CAP11XX RightTouch product portfolio, providing a wide variety of slider, button and proximity functionality. Additionally, the CAP12XX controllers make it easy for designers to add aesthetically pleasing, low-cost touch interfaces. This new six-member family is available in 8- to 16-pin packages.

The CAP12XX family serves a wide range of applications in consumer electronics, such as tablets, printers, audio players, small appliances and televisions; and in the automotive market for automotive interior controls, central stack and overhead lights; as well as other applications.

The family provides designers with improved proximity performance and 3,3 V to 5 V operation. It is also a lower-cost option when integrated LED drivers are not required. To support the new devices, Microchip has also introduced the CAP1298 Evaluation Board (DM160223) and CAP1188 Evaluation Board (160222).
