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.
