Capacitive Touch Sensing ICs Cut Product Development Time
Wed, 06/18/2008 - 1:06pm
The value added, program-driven 8-channel and 16-channel LF versions are now available. This family of products measures floating capacitance through most insulating touch panel materials. They are designed for medical use, and can be easily operated by personnel wearing thin polymer surgical or food service gloves. The B6TS series integrates detecting and processing functions into a single-chip micro controller that can be programmed quickly and easily. The Workbench model B6TW is an intuitive tool enabling design-to-function verification. The products are useful for OEMs & ODMs who produce multiple product variations. Unlike membrane switches, they require no special tooling. The B6TS is available in four versions. All versions feature high noise-immunity and automatic drift compensation. Also, the three LT & LF types have a VDD range of 3.0 to 5.5 VDC. Their operating temperature range is –20 to 85°C.
