AT42QT2160-MMU Description

Short technical summary and product information.

AT42QT2160-MMU is a capacitive touch sensor integrated circuit manufactured by Atmel. It supports button and slider configurations with up to 16 inputs, and communicates over an I²C interface with 10-bit resolution. The device includes 11 LED driver channels for direct feedback to touch functions.

 

The sensor operates from a supply voltage of 1.8V to 5.5V, with typical supply current of 1.127mA. It is designed for surface mount applications and is offered in a 28-VFQFN exposed pad package (supplier device package 28-VQFN 4x4). The operating temperature range extends from -40°C to +85°C.

 

With its configurable input count and I²C interface, the AT42QT2160-MMU suits human-machine interface applications such as touch keypads, slider controls, and combined button/LED systems. The integrated LED drivers reduce external component count in backlit panel designs.
