MAGNETS • MATERIALS • MEASUREMENT New 14-Bit Magnetic Encoder Makes Accurate Angle Measurement For Microcontroller Users bination of large beam currents with a small probe size at any accelerating voltage. Designed for the budgetconscious lab, the JSM7100F model is a versatile, analytical field emission SEM that offers a new level of expanded performance. Through the unique in-lens field emission gun, the SEM delivers ≥ 200 nA of beam current to the sample. An aperture angle control lens (ACL) automatically optimizes both small probe current spot size for high resolution imaging and spot shape for high beam current, high resolution microanalysis, while a beam deceleration mode curtails charging on nonconductive specimens such as ceramics, semiconductors and polymers. The JSM-7100F series is equipped with a large specimen chamber that accommodates a wide variety of detectors and accessories simultaneously and without compromising the performance of one another, including multiple EDS, WDS, STEM, BSE, CL and IR camera. The system can also be equipped with a variety of sub stages including tensile, heating and cooling stages for in situ experimentation. austriamicrosystems has released the AS5048, a 14-bit magnetic encoder IC offering new features that make it easier to achieve accurate, reliable angle measurements in microcontroller-based applications. The AS5048, which provides a PWM output and either an SPI or I2C interface, supplies absolute angle measurements to a host microcontroller. The application’s mechanical design does not need to allow for precise initial alignment of the sensor IC and the two-pole magnet it is paired with. Instead, the zero position is programmed into the AS5048 magnetic encoder one time only on assembly, via a simple SPI or I2C command, with no requirement for a special programming device. The AS5048 is also highly tolerant of misalignment between the sensor IC and its paired magnet and of variations in the air gap, as well as of variations in temperature from -40°C to 150°C. The AS5048 magnetic rotary encoder offers more precise measurement than previous members of austriamicrosystems’ family of magnetic rotary encoders. Its 14-bit measurement engine provides for resolution down to 0.0219°. With linearization and averaging implemented in the host microcontroller, it can deliver angle measurements accurate to 0.05°. Like austriamicrosystems’ existing magnetic encoders, this new device rejects interference from stray magnetic fields, because of the unique Introduces the design of the IC’s integrated Hall sensors and sigSMD Molded High Current Power Inductors nal processing circuitry. This makes the AS5048 well suited for use in electrically and magnetically noisy industrial and medical environments. An internal voltage regulator enables the AS5048 to operate from either a 3.3 V or 5 V supply. It is available in a 14-pin TSSOP package. Multiple devices can be daisy-chained to produce a serial data read-out.
