Analog Front End Adds Inductive Touch Sensing Technology to User Interfaces
Microchip Technology introduced its MCP2036 Analog Front End (AFE) for inductive touch-sensing applications. Complimenting the Company’s royalty-free mTouch inductive touch-sensing solutions, the fully-integrated MCP2036 AFE works with almost any 8-, 16- or 32-bit PIC MCU or dsPIC DSC. This inductive-touch AFE includes a multiplexer, a frequency mixer, an amplifier, a driver, and a voltage reference. It can be configured for a variety of applications in the appliance, industrial and automotive markets, among others. Inductive touch sensing’s fundamental operating principles enable it to work through a front panel, such as plastic, stainless steel or aluminum. The technology also works through thick gloves and on surfaces where liquids are present. The MCP2036 AFE is available in a 16-pin, 4 mm x 4 mm QFN package, as well as 14-pin PDIP and SOIC packages. The device is priced starting at $0.33 each, in 10,000-unit quantities.
