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.
