The AT42QT1011 is a digital burst mode charge-transfer capacitive touch sensor designed for applications requiring touch or proximity detection. It features a single key that can be configured as either a touch sensor or a proximity sensor, making it versatile for various human interface applications such as control panels, consumer appliances, and toys. The device operates within a voltage range of 1.8V to 5.5V and consumes a typical supply current of 378.5 ¬µA. The sensor utilizes patented QTouch technology, which includes self-calibration, auto drift compensation, and noise filtering to ensure stable performance under varying conditions. It supports a maximum on-duration that is infinite, allowing for flexible usage scenarios. The AT42QT1011 is packaged in an 8-pin UDFN/USON format, compliant with RoHS standards, and is suitable for surface mount technology (SMT) applications. With a temperature operating range of -40¬8C to 85¬8C and a moisture tolerance enhanced by its design, this sensor is well-suited for environments where reliability is critical. The device is also compatible with various electrode materials and substrates, providing design flexibility for engineers.
