High Precision Linear Hall-Effect Sensor With an Open Drain Pulse Width Modulated Output
High Precision Linear Hall-Effect Sensor With an Open Drain Pulse Width Modulated Output
A1356
This device is no longer in production. The device should not be purchased for new design applications. Samples are no longer available. The A1356 is a high-precision, programmable open-drain Hall-effect linear sensor IC with a PWM output. It converts analog signals to digitally encoded PWM for superior noise immunity, featuring precision temperature compensation and high-frequency dynamic offset cancellation for accurate, fast signal processing.
