TAD Series
High-Precision TMR Angle Sensors with Digital Output
Based on the Tunnel Magneto-Resistive (TMR) effect, TAD Series angle sensors allow an absolute
angle measurement of up to 360°, offering high sensitivity and best angle accuracy needed for
demanding automotive and industrial applications.
The internal digital signal processing allows outstanding angular measurement performance,
stability in a wide temperature range and increased functionality.
The sensors are pre-calibrated at manufacturing and additionally offer in-application calibration
modes. The “Static compensation” targets the elimination of angle errors caused by mechanical
misalignment between magnet and sensor.
In 360° multi-turn operation, TAD series sensors achieve excellent angle accuracy by using the
“Dynamic compensation” mechanism, which eliminates magnetic, temperature, and life-time ef-
fects. They support various output Interfaces such as UVW (Hall Switch Emulation Mode), PWM,
ENC (Encoder Mode or ABZ), SPI, and SENT.
To reduce system costs and provide automotive system level EMC/ESD protection, one variant
also integrates six capacitors and one resistor.
