Analog Front End enables inductive touch sensing.
June 12, 2009 -
Designed to work with 8-, 16-, or 32-bit PIC® microcontroller or dsPIC® Digital Signal Controller, Model MCP2036 includes multiplexer, frequency mixer, amplifier, driver, and voltage reference. Inductive touch sensing works through plastic, stainless steel, or aluminum front panel, as well as through thick gloves and on surfaces where liquid is present. Housed in 16-pin 4 x 4 mm QFN package and 14-pin PDIP and SOIC packages, AFE is suited for appliance, industrial, and automotive markets.

Microchip Technology Unveils Inductive Touch Sensing Analog Front End (AFE)
Fully Integrated AFE Makes it Easier and More Cost Effective to Develop Inductive Touch Sensing User Interfaces
CHANDLER, Ariz., June 9, 2009 [NASDAQ: MCHP] - Microchip Technology Inc., a leading provider of microcontroller and analog semiconductors, today announced from the Sensors Expo in Chicago the MCP2036 Analog Front End (AFE) for inductive touch-sensing applications. Complimenting the Company's royalty-free mTouch(TM) Inductive Touch-Sensing Solutions, the fully-integrated MCP2036 AFE works with almost any 8-, 16- or 32-bit PIC® microcontroller (MCU) or dsPIC® Digital Signal Controller (DSC), making it even easier and more cost effective for designers to enhance user interfaces with inductive touch-sensing technology. This inductive-touch AFE includes a multiplexer, a frequency mixer, an amplifier, a driver, and a voltage reference, which drastically lowers component count, and reduces design size and cost. Additionally, the AFE can be easily 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. These characteristics make inductive touch sensing suitable for applications in the appliance market because of the possibility of a stainless steel front panel; the industrial market because of the technology's robustness; and the automotive market because of the technology's sleek aesthetics and ability to reduce accidental-touch triggers.
"Microchip's inductive-touch technology provides unique capabilities that complement our capacitive touch-sensing products," said Steve Drehobl, vice president of Microchip's Security, Microcontroller and Technology Development Division.
Drehobl continued, "With the MCP2036 AFE, we are continuing to make it easier and less expensive for engineers to make use of these unique features for applications requiring metal finishing and robust operation in wet environments."
