The A19350 is a giant magnetoresistance (GMR) integrated circuit (IC) providing a user-friendly two-wire solution for applications requiring speed and direction information. It features high sensitivity GMR sensor elements and high precision BiCMOS circuits for accurate, low magnetic field operation. The integrated capacitor enhances EMC robustness, while the SolidSpeed Digital Architecture ensures performance under extreme system-level disturbances, including vibration immunity. This IC offers flexible orientation for xMR or Hall replacement and achieves an ASIL B(D) rating through integrated diagnostics and a certified safety design process. Its two-wire current source output pulse-width protocol supports speed, direction, and ASIL, with an integrated EEPROM for device traceability.
