MC34940 Electric Field Imaging Device

www.DataSheet4U.com Freescale Semiconductor Technical Data Document order number: MC34940 Rev 2.0, 2/2006 Electric Field Imaging Device The 34940 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 34940 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 h.
