AMR1503 AMR Omnipolar Switch Sensor
AMR1503 is a digital omnipolar magnetic switch that integrates Magneto-resistance and CMOS technology to provide a magnetically triggered digital switch with high sensitivity, high speed, and low power consumption. It is designed for pneumatic cylinder position sensing in industrial applications. It contains a push-pull full-bridge MR sensor and CMOS signal processing circuitry within the same package, including an on-chip voltage generator and MR voltage amplifier and comparator for precise magnetic sensing, plus a Schmitt trigger to provide switching hysteresis for noise rejection, and CMOS push-pull output. An internal band gap regulator is used to provide a temperature compensated supply voltage for internal circuits, permitting a wide range of supply voltages. The AMR1503 operates in low voltage and draws only 40μA resulting in low power operation. It has fast response, accurate switching points, excellent thermal stability, and immunity to stray field interference. It is available in the DFN2x2x0.55 -3L package.
