ELECTRIC FIELD
IMAGING DEVICE
Electric Field Imaging Device
The 33794 is intended for applications where noncontact sensing of objects
is desired. When connected to external electrodes, an electric field is created.
The 33794 is intended for use in detecting objects in this electric field. The
IC generates a low-frequency sine wave. The frequency 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 33794 also contains support circuits for a microcontroller unit (MCU) to
allow the construction of a two-chip E-field system.
