Freescale Semiconductor  
Technical Data  
Electric Field Imaging Device  
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 a microcontroller unit (MCU) to allow the  
construction of a two-chip E-field system.
