DESCRIPON
The TSC2007-Q1 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.
