Interface - Sensor, Capacitive Touch

Category Introduction

Products in this family provide the analog stimulus and measurement resources needed to operate a capacitance-based touch sensing transducer, and communicate information generated thereby in a format convenient for use with a microcontroller or similar device, such as an I2C or SPI serial interface, UART, or a simple logic signal. They are commonly used for human interface applications.
