产品概述

The AT42QT1070-SSU is a digital burst mode charge-transfer capacitive Sensor Driver. The device can sense from one to seven keys, dependent on mode. It has the optimized architecture where no external components are required and only 1-pin per channel. It includes all signal processing functions necessary to provide stable sensing under a wide variety of changing conditions and the outputs are fully de-bounced. It modulates its bursts in a spread-spectrum fashion in order to heavily suppress the effects of external noise and to suppress RF emissions. It uses a dual-pulse method of acquisition. This provides greater noise immunity and eliminates the need for external sampling capacitors, allowing touch sensing using a single pin.
  • Comms and standalone mode configurations
  • 1 to 7 keys (or 1 to 6 keys plus a guard channel) comms mode
  • 1 to 4 keys plus a fixed guard channel on key 0 standalone mode
  • 5-output standalone mode
  • Patented spread-spectrum charge-transfer technology
  • 6 x 6mm or Larger (Panel Thickness Dependent), Widely Different Sizes and Shapes Possible
  • 1 PCB layer required
  • Etched copper, silver, carbon and indium tin oxide (ITO) electrode materials
  • Plastic, Glass, Composites and Painted surfaces possible Panel Materials
  • Up to 10mm glass, up to 5mm Plastic (electrode size dependent) panel thickness
  • Individually settable via simple commands over I²C-compatible interface Comms mode
  • Discrete detection outputs interface
  • Self-calibration, auto drift compensation, noise filtering, adjacent key suppression® (AKS®)
