QT140-AS Overview
The packaging uses materials from Tube. Surface Mount is used for mounting it on the PCB. 28-SSOP (0.209, 5.30mm Width) is extremely popular in the electronic industry due to its low package cost. 3V~5.5V Supply Voltage is required for the device to operate normally. It is used to input values of Up to 4. In standard grade applications, it belongs to Type Buttons. A constant -40°C~105°C temperature should be maintained for its operation. Featuring the best cost-down performance ratio on the market, the QProx?, QTouch? Series is the most cost-effective option. This system is supplied with current by 2.5mA. It has a 14 b resolution. Up to 4 channels are used by LED drivers. The supplier device has the package 28-SSOP.
