high performance needs great design. Datasheet: AS5261 12-Bit Automotive Angle Position Sensor Please be patient while we update our brand image as austriamicrosystems and TAOS are now ams. www.ams.com AS5261 12-Bit Automotive Angle Position Sensor 1 General Description 2 Key Features 360 contactless high resolution angular position encoding The AS5261 is a contactless magnetic angle position sensor for accurate angular measurement over a full turn of 360. A sub range User programmable start and end point of the application region can be programmed to achieve the best resolution for the + linearization. application. It is a system-on-chip, combining integrated Hall User programmable clamping levels and programming of the elements, analog front end, digital signal processing and best in transition point. class automotive protection features in a single device. Wide temperature range: - 40C to + 150C To measure the angle, only a simple two-pole magnet, rotating over the center of the chip, is required. The magnet may be placed above Small Pb-free package: MLF 16 6x6 (with dimple) or below the IC. Broken GND and VDD detection The absolute angle measurement provides instant indication of the magnets angular position with a resolution of 0.022 = 16384 positions per revolution. According to this resolution the adjustment 3 Benefits of the application specific mechanical positions are possible. The angular output data is available over a 12 bit PWM output. Unique fully differential solution The AS5261 operates at a supply voltage of 5V and the supply and Best protections for automotive applications output pins are protected against overvoltage up to +20V. In addition Easy to program the supply pins are protected against reverse polarity up to 20V. Additional linearization points for output characteristic Figure 1. Typical Arrangement of AS5261 and magnet Ideal for applications in harsh environments due to contactless position sensing Robust system, tolerant to magnet misalignment, air gap variations, temperature variations and external magnetic fields High inherent accuracy Stacked die redundant approach 4 Applications The AS5261 is ideal for automotive applications like throttle and valve position sensing, gearbox position sensor, pedal position sensing and contactless potentiometers. www.ams.com Revision 1.1 1 - 32
