Expanding the CAP11XX RightTouch product portfolio, Microchip Technology has announced a new family of turnkey capacitive touch controllers, the CAP12XX family. Offering a wide variety of slider, button and proximity functionality, the six-member CAP12XX controller family make it easy for designers to add aesthetically pleasing, low-cost touch interfaces.

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. Operating from 3.3V to 5V, the new family provides designers with improved proximity performance and it also offers a lower-cost option when integrated LED drivers are not required.
