The ZL2003 is a 4-wire resistive touch screen controller. It also features direct measurement of two batteries, two auxiliary analog inputs, temperature measurement, and touch pressure measurement. The ZL2003 has an on-chip 2.5V reference that c an be utilized for the auxiliary inputs, battery monitors, and temperature measurement modes. The reference can also be powered down when not used to conserve power. The internal reference will operate down to 2.7V supply voltage while monitoring the battery voltage from 0.5V to 6V.The ZL2003 is available in the small TSSOP-16 package and is specified over the –40℃ to +85℃ temperature range. 具體詳情可登錄：http://www.zlmicro.com/ 查閱規(guī)格書PDF；
