Product introduction

MC34940EG إغلاقsensor

The MC34940 is suitable for cost-sensitive applications that require non-touch sensing of objects. When an external electrode is connected, an electric field is generated. The MC34940 detects objects in this electric field. Integrated circuits produce low-frequency sine waves whose frequency can be adjusted by external resistors and optimized to 120 kHz. The sine wave has a very low harmonic content, which helps to avoid harmonic interference. The MC34940 also contains microcontroller unit (MCU) support circuitry to create a two-chip electric field system.
