| - | [[ADI>CN0332]] is a single-supply low cost, high-speed magnetoresistive (MR) signal conditioner with a minimum PCB footprint. The complete signal conditioning solution amplifies the small output voltage of the magnetoresistive 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. | + | CN0332 is a single-supply low cost, high-speed magnetoresistive (MR) signal conditioner with a minimum PCB footprint.
