MC34940 Datasheet (Freescale Semiconductor) - Electric Field Imaging Device

MC34940, Electric Field Imaging Device

www.DataSheet4U.com Freescale Semiconductor Technical Data Document order number: MC34940 Rev 2.0, 2/2006 Electric Field Imaging Device The 34940 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 34940 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.
