AccuTouch/AT4 COACh IIs Chip Controller

The COACh IIs (Controller On A Chip, second generation) (Part # E705204, RoHS Compliant) is a compact, lower-power controller chip for AccuTouch five-wire and AT4 four-wire resistive applications. It operates at both 3.3V and 5V, and is packaged within a small footprint of 12.15 mm x 12.15 mm. The COACh IIs also incorporates a power-down mode in which power consumption can be reduced by as much as 95%. The compact size, lower operating voltage, and reduced power consumption of the COACh IIs makes it as the best solution for OEMs who have been looking for stability, reliability and performance of the touch components for the embedded and portable applications. The COACh IIs is also fully compatible with the Elo SmartSet protocol and all program drivers.
