Medical Imaging 18.14 Capacitive Sensing and Touch Screen Display The MC34940 is intended for cost-sensitive applications where non-contact sensing of objects is desired. When connected to external electrodes, an electric field is created. The MC34940 detects objects in this electric field. The IC generates a low-frequency sine wave, which is adjustable by using an external resistor and is optimized for 120 kHz. The sine wave has very low harmonic content to reduce harmonic interference. The MC34940 also contains support circuits for an MCU to allow the construction of a two-chip E-field system. For more information about touch panel applications, see the application note titled Touch Panel Applications Using the MC34940/ MC33794 E-Field IC (document AN1985), available at freescale.com. For wireless communication, power management, keypad and speaker implementation modules, see Chapter 3 Telehealth Systems Introduction.
