Sensor, Capacitive Touch
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.
Sourcing ROHM Semiconductor Sensor, Capacitive Touch: in-stock lines for quick ship, BOM matching for multi-line builds, and original-channel screening — not keyword stuffing.
