General description
The MagnetoResistive (MR) sensor with integrated amplifier is designed for angular control applications and BrushLess DC (BLDC) motors with even-numbered pole pairs. It consists of two microchips within one package, an angle sensor and an amplifier Integrated Circuit (IC). The circuit delivers cosine and sine output signals related to the angle of a rotating magnetic field. The output voltage range is ratiometric related to the supply voltage. The Temperature Coefficient (TC) of the sensor amplitude can be compensated. A ratiometric output voltage linear to the temperature is delivered. A Power-down mode is implemented.

Features and benefits
◾ High precision sensor for magnetic angle measurement
◾ Single-ended cosine and sine outputs
◾ Ratiometric output voltages
◾ Tamb = 40 °C to +150 °C
◾ Temperature compensated output signal amplitude
◾ Temperature related ratiometric reference voltage
◾ Power-down mode to enable or disable the device
