TSC2000中文资料具有 8/10/12 位 125Khz ADC 和 SPI 接口的 4 线可编程触摸屏控制器数据手册TI规格书

描述 Description

The TSC2000 is a complete PDA analog interface circuit. It contains a complete 12-bit, Analog-to-Digital (A/D) resistive touch screen converter including drivers, the control to measure touch pressure, and an 8-bit Digital-to-Analog (D/A) converter output for LCD contrast control. The TSC2000 interfaces to the host controller through a standard SPI™ serial interface. The TSC2000 offers programmable resolution and sampling rates from 8- to 12-bits and up to 125kHz to accommodate different screen sizes.
The TSC2000 also offers two battery-measurement inputs, one of which is capable of reading battery voltages up to 6V while operating at only 2.7V. It also has an on-chip temperature sensor capable of reading 0.3°C resolution. The TSC2000 is available in a TSSOP-20 package.

简介

TSC2000属于集成电路（IC）的触摸屏控制器。由TI制造生产的TSC2000触摸屏控制器触摸屏控制器是一种集成电路，可在触摸屏传感器阵列与屏幕操作的设备之间提供接口。该控制器从传感器阵列（通常是电阻式或电容式）接收位置信息。然后，位置信息又通过串行、并行、USB 或 UART 接口传递给微控制器。
