AS8580 Capacitive Sensors

Infineon Technologies AS8580 capacitive sensors detect and measure changes in capacitance across different applications. These sensors capture sinusoidal current responses from a forced sinusoidal voltage. This enables accurate identification of capacitive and resistive components, helping compensate for environmental disturbances such as moisture. The Infineon Technologies AS8580 sensors feature a 5MHz to 20MHz dynamic measurement frequency range for advanced EMC robustness and are AEC-Q100 Grade 1 qualified. Typical applications include hands-on steering wheel detection, automotive door handle/trunk opening, human presence detection for automotive and non-automotive, and sensing of fluid level and quality.
