ASR022-10E: ABZ Noncontact TMR Encoder Sensor, TDFN6
ASR022 noncontact TMR encoder sensors provide precise pulses indicating angular motion, and is more accurate and smaller than other non-contact encoders.
An ABZ interface allows the ASR022 to replace legacy optical encoders.
The sensor combines precise, low-power Tunneling Magnetoresistance (TMR) sensing elements with sophisticated digital signal processing.
The sensor is factory calibrated, with coefficients stored in internal memory.
The ASR022 is designed for harsh industrial or automotive environments with ESD protection, and full −40 °C to 125 °C operating temperature range.

SM125-10E: General-Purpose 4 mT Smart GMR Magnetometer, TDFN6
The SM125-10E Smart Magnetometer combines an omnipolar GMR sensor element with
with easy-to-use digital signal processing.
A digital output provides precise, programmable thresholds.
An I²C interface provides magnetic field data, as well as a
calibration interface. The device is factory calibrated for accuracy. Calibration coefficients are stored in internal nonvolatile memory.
All commands, data, and coefficients are a single byte, and a
slick, elegant data structure lets you get up and running with
a minimum of firmware.
Key features include:
• Can detect magnets more than 50 mm away
• I²C and digital threshold outputs
• 0-4 mT linear range
• 8-bit / 1% output resolution
• −40°C to +125°C operating range
• 5% FS accuracy for 0 to 85°C
• 10 kSps sample rate for fast response
• 6 mA typical supply current
• In-plane sensitivity more usable than Hall effect sensors
• Programmable offset and gain compensation
• Optional magnet temperature compensation
• 2.2 to 3.6 volt supply
• Ultraminiature 2.5 x 2.5 x 0.8 mm TDFN package
