High Precision, Programmable Linear Hall Effect Sensor IC with EEPROM, SENT and PWM Output Protocols, and Advanced Output Linearization

A1341

This device is no longer in production. The device should not be purchased for new design applications. Samples are no longer available. The A1341 is a high-precision, programmable Hall-effect linear sensor IC with configurable PWM or SENT output, 12-bit resolution, and up to 3kHz bandwidth. It features advanced temperature compensation, dynamic offset cancellation, 32-segment linearization, and on-board EEPROM for flexible customization.

Product Details

Top Features
