Datasheet Summary
Freescale Semiconductor Technical Data
Electric Field Imaging Device
The MC33794 is intended for applications where noncontact sensing of objects is desired. When connected to external electrodes, an electric field is created.,The MC33794 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 MC33794 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...
