The MT6301 Touch-Screen Controller IC is a 12-bit successive approximation ADC with synchronous serial
interface and low on resistance drivers for 4-wire resistive touch screens. MT6301 operates from a single
2.6V to 5.5V power supply and dissipate typical 700uW power at 125 KHz throughput rate and a 2.8V supply.
The reference voltage can be varied from 1V to Vdd, while the analog input range is from 0V to Vref. The
supply current is below 1uA at power-down mode.
With the proprietary power-saving technique, the ON time of the driver switches could be shorten to
alleviate power dissipation on the touch screen device in ratio-metric conversion operation. It is especially
benefic when the sampling rate is high.
With the low power, high speed, and integrated driver switches features, the MT6301 is ideal for batteryoperated
portable equipments such as mobile cellular phones, personal digital assistants with resistive
touch screen features.
