The CAP1128-1-BP-TR is an 8-channel capacitive touch sensor from Quarktwin Technology Ltd. It features programmable sensitivity and automatic recalibration to adapt to environmental changes. Each of the eight sensor inputs can be individually configured with specific thresholds, and the device supports multiple button pattern detection, allowing for simultaneous touches. Additionally, the CAP1128 includes two LED drivers that can be linked to sensor inputs for visual feedback, offering functionalities such as variable blinking, dimming, and breathing effects. The device operates with low power consumption, drawing a typical quiescent current of 5 µA in deep sleep mode and 50 µA in standby mode while monitoring one sensor input. Communication interfaces include SMBus/I2C and SPI, with the ability to select between multiple slave addresses. The product is housed in a 20-pin 4mm x 4mm QFN package and is suitable for applications in desktop and notebook PCs, LCD monitors, consumer electronics, and appliances.
