The operates down to 2.2V supply voltage and supports digital I/O interface voltage from 1.5V to VCCin order to connect low voltage uP.
The TCS2046 can detect the pressed screen location by performing two A/D conversions. In addition to location,the TCS2046 also measures touch screen pressure.On-chip VREF can be utilized for analog auxiliary input,temperature measurement and battery monitoring withthe ability to measure voltage from 0V to 5V.
The TCS2046 also has an on-chip temperature sensor
The TCS2046 is available in 16pin QFN thin package(0.75mm in height) and has the operating temperature range of -40°C to +85°C
]]>TCS2007 能通過執(zhí)行兩次A/D 轉(zhuǎn)換查出被按的屏幕位置, 除此之外,還可以測量加在觸摸屏上的壓力。內(nèi)部自帶 2.5V 參考電壓。在2.7V 的典型工作狀態(tài)下,關(guān)閉參考電壓,功耗可小于0.75mW。
