Hynitron Microelectronics CST328 High performance mutual capacitance multi-touch chip 1. Overview The CST328 series multi-point capacitive touch chip supports single-layer, multi-layer modules and a variety of patterns. It uses a high-voltage drive above 10V to achieve high performance, high sensitivity, and low power consumption for true multi-point touch (with pressure detection). Compared with traditional low-voltage drivers, it can provide higher signal-to-noise ratio and anti-interferen.
