S3930 Series Touch Controller
S3930
S3930 series extends technology leadership into the rapidly expanding foldables segment with the smallest high-performance touch controller for highly responsive OLED display interactions
At the core of the S3930 series are innovations that can mitigate noise by improving filtering and isolating touch signals. A key enabler is Synaptics’ patents around multi-frequency-region parallel sensing (MFRPS). This technique reduces sensing bursts required for large touch sensors. It uses continuous time sensing with a digital analog front-end (dAFE), making multi-frequency decoding more efficient and cost-effective.
