Magnetic Rotary Encoder ICs by austriamicrosystems Power US

austriamicrosystems supplies AS5040, the 10-bit magnetic rotary encoder IC, to US Digital for
their first magnetic absolute shaft encoder product

Unterpremstaetten, Austria (January 12, 2007) - austriamicrosystems (SWX: AMS), a leading global designer
and manufacturer of analog integrated circuits (ICs) for industrial, medical, communication, and automotive
applications, supplies AS5040, the 10-bit magnetic rotary encoder IC, to US Digital, a specialist in motion control
products, for their first magnetic absolute shaft encoder product.

The MA2 absolute magnetic shaft encoder by US Digital is based on austriamicrosystems' AS5040 device which,
due to its contactless measurement method, makes MA2 a highly reliable product, immune to adverse
environmental conditions such as dust, moisture, vibration or elevated temperature conditions. With the MA2, US
Digital launches their first absolute magnetic shaft encoder as a complement to their range of well established
optical encoder products for motion control, factory automation and robotics.

"Our close collaboration with US Digital over many years has significantly helped us to bring to the market
innovative products which exactly meet market demand," said Matjaz Novak, Marketing Director Industry &
Medical at austriamicrosystems. "The AS5040 based MA2 product is a perfect example of the exciting new
solutions our magnetic sensing technology brings to our customers. We look forward seeing further creative
products emerging out of our partnership with US Digital".

"We are excited to be working with austriamicrosystems with their new absolute AS5040 series encoder
technology," said David Madore, CEO of US Digital. "This magnetic encoder technology enables us to offer
practical, low cost absolute encoders available with either Analog or Pulse Width Modulation outputs".

The AS5040 360-degree magnetic rotary encoder IC is a true system-on-chip, integrating field sensing Hall
elements and signal processing. The rotary position is sensed contactlessly by a small rotating magnet that is
placed above the device. The AS5040 can detect 1,024 absolute positions over a full turn, which corresponds to
a resolution of 0.35 degrees. Additional features include a user programmable zero/index position and a safety
feature that constantly monitors the presence of the magnet.
