The LDS6124NQGI is a one-channel self-capacitance input multiplexer that provides a simple and cost-effective solution for the design of capacitive touch systems. The device offers an optimized capacitive touch solution for applications such as automatic fan speed control, monitors and LED lighting. The LDS6124NQGI is designed to work in conjunction with capacitive-sensing controllers such as the Industry Standard TMA300C and LTC2256C.This device can be used in a wide range of applications such as pressure, temperature and digital touch sensing for industrial, commercial and consumer-oriented products. It can also be used for digital audio and video applications, as well as for display and user interface applications. The LDS6124NQGI provides digital outputs that allow for the monitoring and control of up to eight external touch buttons and provides a full support of active sensing technologies, such as, scan-thru and sequential scanning. The device is compatible with both 5-bit and 8-bit data as well as an analogue-to-digital conversion.The LDS6124NQGI provides various features that make capacitive touch systems easier to design and use. It has a low power mode, which reduces power consumption, and a check-back feature to help avoid misread inputs. It also has an interrupt output pin (INT) that can be used to indicate when a touch has occurred.The LDS6124NQGI is also designed with an input finite resistance shielding feature, which helps reduce noise susceptibility and improves system accuracy and reliability. The working principle of the LDS6124NQGI is based on the principle of self-capacitance. Self-capacitance is a type of capacitance that occurs between two conductive elements that are placed near one another. As one of the elements is touched, the capacitance between them increases, and the device detects this change and converts it into a digital signal that is used to drive the desired output.The LDS6124NQGI is a cost-effective way to implement capacitive touch sensing into a design. Its low power current and high performance makes it well-suited for a variety of applications, including home and industrial automation, automotive, medical and consumer electronics applications.
