AT42QT1110-MUR Overview
The packaging uses materials from Tape & Reel (TR). Using Surface Mount, it can be mounted on the PCB. Its low package cost accounts for much of 32-VFQFN Exposed Pad's popularity in the electronic industry. In order to ensure its normal operation, it needs the 3V~5.5V Supply Voltage. A Up to 11 input is used. Standard grade applications are classified as type Buttons. The temperature should always be kept at -40°C~85°C during operation. Featuring the best cost-down performance ratio on the market, the QTouch™ Series is the most cost-effective option. For this system, the supply current comes from 10mA. A part's resolution is 10 b. Drivers for LEDs have -- channels. This is constructed by terminating 32. There is always a 5V volt supply powering the component. Voltage supply, Vsup, must be greater than voltage demand, 3V. The supplier device has the package 32-QFN (5x5). Vsup reaches its maximum at 5.5V. There are 11 Channel channels for transmitting data. In order for it to operate, 3 V to 5.5 V voltage must be supplied. It falls under the Sensors subcategory.
