Magnetic Encoder ICs suit motion control applications.
September 12, 2008 -
Providing start/play solution for motion control applications as they require no configuration or calibration by host controller after power up or during operation, Models AS5304 and AS5306 can achieve resolutions of 25 and 15 µm, respectively. Immune to dirt, dust, and grime contaminants to meet reliability challenges in harsh environments, linear Hall sensor ICs are available in 20-lead 5 x 5 mm TSSOP and specified to operate at 5 V over temperature range of -40 to 125°C.

austriamicrosystems Introduces AS5304 and AS5306, Two New Start & Play Incremental Linear Magnetic Encoder ICs for Motion Control Applications
AS5304 and AS5306 provide motion control developers with alternative solutions to optical encoders to meet reliability challenges associated with harsh environments
Unterpremstaetten, Austria (September 8, 2008) - austriamicrosystems (SWX: AMS), a leading global designer and manufacturer of high performance analog ICs for communications, industrial, medical and automotive applications, today expanded its magnetic sensor product portfolio to include the AS5304 and AS5306, two high
performance linear Hall sensor ICs.
The AS5304 and AS5306 ICs feature austriamicrosystems' new line of magnetic encoders for linear and off axis motion sensing applications. The devices provide an easy-to-use, start & play solution for motion control applications as they require no configuration or calibration by the host controller after power up or during operation.
The new linear magnetic encoder IC's can be used in a variety of motion sensing applications found in medical, industrial and consumer products.
"The measurement performance and reliability of motion control systems employing traditional optical encoder sensors can be severely impacted by dirt, dust and grime contaminants. Due to the principles of magnetic sensing, the AS5304 and AS5306 encoder ICs are immune to these contaminants and can therefore significantly contribute
to a higher reliability of motion control applications", says Matjaz Novak, Marketing Director Industry & Medical at austriamicrosystems.
Similar to optical sensors, the AS5304 and AS5306 provide incremental A & B quadrature output signals with 160 steps per magnet pole pair, and an index pulse that is applied once every pole pair. The index pulse together with the quadrature output signals allow designers to develop applications that track the absolute position once
referenced from a known starting position after power up.
The AS5304 and AS5306 ICs can achieve resolutions of 25µm and 15µm, respectively.
In addition to standard linear positioning applications where a magnet strip moves laterally from left to right or vice versa over the IC, the AS5304 and AS5306 encoder ICs also support rotary off axis applications by using a circular ring magnet mounted on the outside of a rotating shaft. Rotary off axis encoding solutions can be used in
applications where the magnet cannot be placed directly at the end of a rotating shaft due to mechanical constraints.
The AS5304 and AS5306 devices are available in a 20-lead 5x5mm TSSOP device and are specified to operate at 5V over a temperature range of -40C to +125C. Product information including datasheets and application notes is available at http://www.austriamicrosystems.com/Li...
