MC33794 Electric Field Imaging Device

Pin 1 2, 5, 27, 43 3 Pin Name VCC NC AGND Formal Name 5.0 V Regulator Output No connect Analog Ground Definition This output pin requires a 47 µF capacitor and provides a regulated 5.0 V for the MCU and for internal needs of the 33794. These pins may be used at some future date and should be left op.

MOTOROLA SEMICONDUCTOR TECHNICAL DATA Document order number: MC33794/D Rev 6.0, 04/2003 Product Preview 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. T.
