33794

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.

ELECTRIC FIELD

IMAGING DEVICE

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.

Features

• Supports up to 9 Electrodes and 2 References

• Shield Driver for Driving Remote Electrodes Through Coaxial Cables

• +5.0 V Regulator to Power External Circuit

• ISO-9141 Physical Layer Interface
