QT140-ASG Overview
It is packaged using materials from Tape & Reel (TR). It is mounted on the PCB using Surface Mount. Low package costs are one of the reasons for 28-SSOP (0.209, 5.30mm Width)'s popularity in the electronic industry. In order for it to operate normally, it requires the 3V~5.5V Supply Voltage. We use Up to 4 inputs. Type Buttons is for applications of standard grade. In order for it to operate properly, it should always have a temperature of -40°C~105°C. With the best cost-down performance ratio on the market, the QProx™, QTouch™ Series provides the best value for your money. This system is powered by 2.5mA. 14 b is the resolution of the part. LED drivers use Up to 4 channels. Supplier device package 28-SSOP.
