Atmel's Data Acquisition products for Touch Screen applications

Atmel

Building on 15 years of Atmel® touch innovation, maXTouch™ is the next-generation controller technology for touchscreen applications that delivers both superior performance and low power consumption.

Product Description

The technology enables touch interfaces that identify, qualify, and track the user’s contacts with exceptional precision and sensitivity. With maXTouch™ unlimited touch, users can enjoy a sophisticated interface that is smart enough to ignore unintended touches. Atmel touchscreen chips are small enough to fit the most compact mobile devices and powerful enough to accommodate the larger screens on products such as digital tablets. The result: peerless touch interfaces that are intuitive, flexible, reliable, and battery-friendly.

Features
  • Unlimited touch — This unique maXTouch™ capability enables advanced functions invoked by simultaneous multiple touches, and helps avoid false touches.
  • Active stylus — With a high-performance 1mm tip, maXStylus active stylus offers the convenience of pen-like operations on the touchscreen.
  • Fast response — High scan rates enable devices to follow virtually any motion, supporting demanding applications.
  • Exacting precision — An advanced, low-noise front end and numerous sensor nodes make the screen more precise and sensitive to contact.
  • Unparalleled flexibility — The chips can be easily configured to suit a broad array of applications and screen sizes.
  • Low power consumption — ICs "sleep" after scans to conserve power and extend battery life.
  • Small footprint — Chips are suitable for the smallest devices and require few external components, lowering system costs.
  • Robust operation — Environmental resilience and excellent noise suppression increase reliability and usability.
Specifications
  • Current - Supply:1.14mA ~ 378.5µA
  • Resolution:9 b ~ 14 b
