Angle sensors and conditioning ICs
NXP's magnetoresistive angle sensors offer clear advantages over devices employing other sensing methods. MR sensors provide an output signal virtually independent of magnet tolerances, magnet temperature coefficients, magnet-sensor distance and positioning tolerances. Achieving high accuracies and performance, these sensors are ideal for a variety of demanding automotive and industrial applications.
The new KMA200 sensor system combines the sensor-head and the conditioning IC in a special multi-chip package. Furthermore each KMA200 is individually pre-calibrated and the system is user programmable for application-oriented output characteristics. Possessing different sensitivity, our KMZ41 and KMZ43 angle sensors are designed to work with the UZZ900x conditioning ICs, which provide either analog or 13-bit SPI interfacing.
