Description

The TMR265x is a tunneling magnetoresistance (TMR)

linear sensor with a dedicated signal conditioning

circuit built in. The integrated signal conditioning

circuit of TMR265x is able to calibrate zero offset,

gain, temperature coefficient of sensitivity (TCS) and

temperature coefficient of zero offset (TCO) of the

TMR bridge circuit, and outputs the conditioned voltage

signals.

In addition to TMR’s intrinsic advantages of high

resolution, high signal-to-noise ratio, and low power

consumption, TMR265x series linear sensors also

provide the following characteristics:

1. Fixed voltage output range in linear range

2. Excellent sensitivity consistency

3. Minimal zero drift

4. Low temperature coefficient of sensitivity

5. Low temperature coefficient of offset

This improvement greatly enhances the convenience

of design and use of TMR linear sensor products.

The TMR265x linear magnetic sensor is available in

DFN6L (3 mm × 2 mm × 0.75mm) package with P/N

of TMR2651D and TMR2652D.
