AT42QT1111-AU - QTouch 11-key Sensor

Download the AT42QT1111-AU datasheet PDF. This datasheet also covers the AT42QT1111-MU variant, as both devices belong to the same qtouch 11-key sensor family and are provided as variant models within a single manufacturer datasheet.

General Description

Table 1-1.

Key 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.
