AT42QT1111-AU - QTouch 11-key Sensor

This page provides the datasheet information for the AT42QT1111-AU, a member of the AT42QT1111-MU QTouch 11-key Sensor family.

Datasheet Summary

Description

Table 1-1.

Features

Sensor Keys:.
Up to 11 QTouch™ channels.
Data Acquistion:.
Measurement of keys triggered either by a signal applied to the SYNC pin or at regular intervals timed by the AT42QT1110's internal clock.
Keys measured sequentially for better performance, or in parallel groups for faster operation.
Raw data for key touches can be read as a report over the SPI interface.
Discrete Outputs:.
Configurable “Detect” outputs indicating i.
