The AMR1341 is a digital omnipolar magnetic switch that integrates magnetoresistance 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 full-bridge push-pull anisotropic magnetoresistance (AMR) sensor and CMOS signal processing circuitry within the same package, including an on-chip voltage generator and 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 AMR1341 operates in low voltage and draws only 40 μA resulting in low power operation. It has fast response, accurate switching points, excellent thermal stability, and immunity to stray field interference. AMR1341 is available in two compact DFN3L (2mm × 2mm × 0.55mm) and LGA3L (2mm × 1.5mm × 0.63mm) packages.
