Technical Data

Electric Field Imaging Device

The MC33941 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 MC33941 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 MC33941 also

contains support circuits for a microcontroller unit (MCU) to allow the

construction of a two-chip E-field system.
