EVAL-CN0332-PMDZ: Magnetoresistive (MR) Rotational Speed Sensor

The circuit on EVAL-CN0332-PMDZ is a single-supply, low cost, and high-speed magneto resistive (MR) signal conditioner with a minimum PCB footprint.

The complete signal conditioning solution amplifies the small output voltage of the magneto resistive sensor and converts it into a digital output signal with a rise and fall time of less than 5 ns and an RMS jitter of approximately 100 ps.

The circuit provides a compact and cost effective robust solution for high speed rotational sensing in industrial and automotive applications and is an excellent alternative to Hall Effect sensors.
