TSC2007IPWR

Product Summary

The TSC2007IPWR is a very low-power touch screen controller designed to work with power-sensitive, handheld applications that are based on an advanced low-voltage processor. It works with a supply voltage as low as 1.2V, which can be supplied by a single-cell battery. It contains a complete, ultra-low power, 12-bit, analog-to-digital (A/D) resistive touch screen converter, including drivers and the control logic to measure touch pressure. The applications of the TSC2007IPWR include: (1)Cellular Phones; (2)PDA, GPS, and Media Players; (3)Portable Instruments; (4)Point-of-Sale Terminals; (5)Multiscreen Touch Control.
