This document introduces the features and characteristics of QT60160 and QT60240, two touch sensor ICs. These two products support 1 to 16 keys and use patented spread-spectrum charge-transfer technology.
The Quantum QT60160 and QT60240 are QMatrix™ touch sensor ICs that support 16‑key and 24‑key matrix layouts respectively. The document provides an overview of the devices, key design guidelines, PCB layout recommendations and detailed command structures for configuring and reading key data.
It describes the I²C slave interface (100 kHz) and optional parallel output, power supply requirements, sample capacitor operation, and calibration procedures, along with practical advice on component selection and EMC considerations for reliable integration into mobile and consumer electronics.
