AT42QT1010 Data Sheet

Introduction

The AT42QT1010 is a digital burst mode charge-transfer sensor that is capable of detecting near

proximity or touch, making it ideal for implementing touch controls.

The QT1010 is designed specifically for human interfaces like control panels, appliances, toys, lighting

controls, or anywhere a mechanical switch or button may be found. It includes all hardware and signal

processing functions necessary to provide stable sensing under a wide variety of changing conditions.

Only a single low-cost capacitor is required for operation.

Features

•

Number of Keys:

– One – configurable as either a single key or a proximity sensor

Technology:

– Patented spread-spectrum charge-transfer (direct mode)

Key outline sizes:

– 6 mm × 6 mm or larger (panel thickness dependent); widely different sizes and shapes

possible

Electrode design:

– Solid or ring electrode shapes

PCB Layers required:

– One

Electrode materials:

– Etched copper, silver, carbon, Indium Tin Oxide (ITO)

Electrode substrates:

Panel materials:

– Plastic, glass, composites, painted surfaces (low particle density metallic paints possible)

Panel thickness:

– Up to 12 mm glass, 6 mm plastic (electrode size and Cs dependent)

Key sensitivity:

– Settable via capacitor (Cs)

Interface:

– Digital output, active high

Moisture tolerance:

– Increased moisture tolerance based on hardware design and firmware tuning

Operating Voltage:
