A1341 Overview
Description
The A1341 device is a high precision, programmable Hall effect linear sensor integrated circuit (IC) with a configurable pulse width modulated (PWM) or single edge nibble transmission (SENT) output, for both automotive and nonautomotive applications. The signal path of theA1341 provides flexibility through external programming that allows the generation of an accurate, and customized output voltage from a input magnetic signal.
