TSC2007IPWR

1.2V至3.6V ， 12位，纳安级，4线微型触摸屏控制器I2C⑩接口 1.2V to 3.6V, 12-Bit, Nanopower, 4-Wire Micro TOUCH SCREEN CONTROLLER with I2C⑩ Interface

DESCRIPON

The TSC2007 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.
