Ultrasonic sensor AFE (Analog Front End) is not a specific brand but a category of electronic components used for signal conditioning in ultrasonic sensing applications. These AFEs are typically produced by semiconductor companies such as Texas Instruments (USA), Analog Devices (USA), and STMicroelectronics (Switzerland/France). They serve industries like automotive, industrial automation, and medical devices, enabling precise distance measurement, object detection, and flow monitoring. Key products include integrated circuits (ICs) for signal amplification, filtering, and analog-to-digital conversion, optimized for ultrasonic frequencies.
