DESCRIPTION

· ADT001 rotation sensors are ultralow power, digital-output magnetic rotation sensors using Tunneling Magnetoresistance (TMR) technology.
· Ideal for battery operation due to small size and low power.
· Features two digital, binary outputs 90 degrees out of phase for directional information.
· Includes an additional output to indicate fault if the magnetic field is too high for accurate measurements.
· Optimized for edge-sensitive applications with high hysteresis for noise immunity.
· Packaged in NVE’s 2.5 mm x 2.5 mm x 0.8 mm TDFN6 surface-mount package.

FEATURES

· Utilizes Tunneling Magnetoresistance (TMR) technology.
· Extremely low power consumption (1.8 μA typical at 2.4 V).
· Precision digital quadrant outputs.
· Wide airgap tolerance.
· Operates with as little as 30 Oersteds of magnetic field.
· Integrated fault detection.
· Supply range from 2.4 V to 5.5 V.
· Operating temperature range from −40°C to +125°C.
· Ultraminiature TDFN6 packages.

APPLICATIONS

· Water meters.
· Rotational speed sensors.
· Rotational position sensors.
