MT9211

The MagnTek® MT9211 product series is a monolithic programmable Hall effect linear sensor IC. The device can be used for accurate positionsensing in a wide range of applications.
Each of the MT9211 consists of a highly sensitive Hall element, a low noise small-signal high-gain amplifier, a clamp and overcurrent protection output stage, and a high bandwidth dynamic offset cancellation technique.
The MT9211 provides an analog output voltage proportional to the applied magnetic flux density.
