DESCRIPTION
The A19250 is a giant magnetoresistance (GMR) integrated circuit (IC) that provides a user-friendly two-wire solution for applications where speed information is required. The small integrated package includes an integrated capacitor and GMR IC in a single overmold design with an additional molded lead-stabilizing bar for robust shipping and ease of assembly.
The GMR-based IC is designed for use in conjunction with front-biased ring magnet encoders. State-of-the-art GMR technology with industry-leading signal processing algorithms accurately switch in response to low-level differential magnetic signals.The high sensitivity of GMR combined with differential sensing offers inherent rejection of interfering common-mode ma...
