austriamicrosystems unveils AS5030 and AS5130, 8-bit Magnetic Rotary Encoder ICs With Push-Button and Low-Power Mode Features.

Ideal Contactless Alternative to Mechanical Rotary Switches for a Variety of Automotive, Industrial and Consumer Applications

UNTERPREMSTAETTEN, Austria -- austriamicrosystems (SWX:AMS), a leading global designer and manufacturer of high performance analog integrated circuits (ICs) has further expanded its rotary encoder family by introducing the AS5030 and AS5130, two 8-bit absolute magnetic rotary encoder ICs with push button and low power mode features. The devices offer a reliable, contactless alternative to mechanical rotary knobs in a variety of automotive, industrial and consumer applications.

The AS5030 and AS5130 provide an angle resolution of 1.4 degrees over a full 360 turn (8-bit), accessible via digital serial interface (SSI) or via pulse width modulated (PWM) outputs. Both devices offer push-button functionality with user defined magnet-to-device displacement thresholds. For use in applications with stringent power consumption requirements, both devices can operate in low-power mode. In addition, the AS5030 offers ultra low power sleep mode, which can be set by user.

"The AS5030 and AS5130 have been specifically designed to offer a low-cost, highly reliable solution for human-machine-interfaces, such as rotary switches, dashboard and appliance knobs," said Josef Janisch, Product Manager Sensors & Automation at austriamicrosystems. "The push-button feature with multi-turn functionality, plus the low power consumption of the AS5030 and AS5130 deliver significant advantages in product design flexibility and product lifetime."

Both devices can be configured to provide data either via serial interface, PWM or daisy chain. The daisy chain configuration enables users to read the position information of individual devices serially, via a single two-wire bus. The ICs operate at 5V supply voltage, cover a temperature range from -40C to +125C, and operate at rotational speeds up to 30,000 rpm.

The AS5030 is available in a lead-free TSSOP16 package while the AS5130 is available in a lead-free SSOP16 package. The AS5030 is available for sampling now and the AS5130 will be available for sampling in the first quarter of 2007.
