Maxim Integrated 

Low-Power, Ultra-Small Resistive Touch-Screen

Controllers with I2C/SPI Interface

ELECTRICAL CHARACTERISTICS (continued)

(VDD = 1.7V to 3.6V, TA = -40°C to +85°C (MAX11800E–MAX11803E), TA = -40°C to +105°C (MAX11800G/MAX11801G), unless oth-

erwise noted. Typical values are at TA = +25°C and VDD = 3.3V, unless otherwise noted.)
