A1301 and A1302: Continuous-Time Ratiometric Linear Hall Effect Sensor ICs

I assumed that the differences were determined by me approaching z1301 retracting the Neodymium magnet from the sensor. Integrating the Hall circuit and the amplifier on a single chip minimizes many of the problems normally associated with low voltage level analog signals. Ambient Temperature Device Sensitivity vs.

1a301 of this device is currently restricted to existing customer applications. Therefore I would like to ask the kind forum members the following questions: Two device package types are available: What kind of magnets is the AllegroA sensible for? What do you mean by “slot”? Units — — 4. Although the application of very high magnetic fields does not damage these devices, it does force their output into a nonlinear region. Please contact the Allegro Marketing department for additional information.

Supply Voltage Device Symmetry vs.

I think your best bet is to decide what you really want to achieve – metal or magnet, choose a different device like the recommended A replacement. Does a magnetic sensor “feel” fluctuations caused by approaching a metal piece to it? The on-chip output stage is designed to provide linear output at a supply voltage of 5 V. However, Allegro MicroSystems, Inc. Just a quick look at the spec suggests that the output is analogue, so digital read may not be much good – I would expect this device to give a voltage output on the output pin, so analogue read would be more appropriate.

These features make the A and A ideal for use in position sensing systems, for both linear target motion and rotational target motion. The information included herein is believed to be accurate and reliable.

Read the data sheet. Good day everyone, I am a new face in the world of Arduino and electronics and I wanted to try my luck with an Allegro A magnetic sensor. This classification indicates that the product is obsolete and notice has been given.

Is there another way to wire the sensor? The device should not be purchased for new design applications because of obsolescence in the near future. A and A Datasheet. They are optimized to accurately provide a voltage output that is proportional to an applied magnetic field.

Two device package types are available: Two output sensitivity options are provided: August 30, Recommended Substitutions: Hall effect “switching” devices provide a digital output depending on the strength of the magnetic field. Hello I think you need to go back to the basics Have you looked at the data sheet for this device?

They are optimized to accurately provide a voltage output that is proportional to an applied magnetic field. For the latest version of this document, visit our website: Conversely, the application of a north polarity —B magnetic field, in the same orientation, proportionally decreases the output voltage from its quiescent value. This proportionality is specified as the magnetic sensitivity of the device and is defined as: Low-noise output Fast power-on time Ratiometric rail-to-rail output 4.

High precision in output levels is obtained by internal gain and offset trim adjustments made at end-of-line during the manufacturing process.

Thereafter I wrote a sketch which checks whether there are voltage fluctuations in the sensor using the digitalread function and then printing the results in the console when I approach a Neodymium magnet towards it.

Allegro are generally pretty good at application notes, so I would start there, before even starting with code. The A and A feature a ratiometric lalegro. You say you want to detect a301 then talk about “magnets” This device gives an output relative to a magnetic field, so a lump of aluminium isn’t going to do much.

Before placing an order, the user is cautioned to verify that the information being relied upon is current. My results show me random numbers varying from to which repeat at regular intervals.

In the quiescent state no significant magnetic field: Are the results voltages or random numbers? There are allero news items available for this product.

Low-noise output Fast power-on time Ratiometric rail-to-rail output 4. Do I have to process the raw data in order to get some better results? Integrating the Hall sensing element and the amplifier on a single chip minimizes many of the problems normally associated with low voltage level analog signals. If this is not your local representative, find your local sales rep here.

Thank you and have a nice week ahead! Click the image to view larger. Because I get the same results when I “read” both an empty slot and the slot with the sensor, is it possible that my sensor is broken? My goal is to make a device that can be used to sense some metal approaching it. A1031 yes, how can I test to find it out?

One of my friends recommended me to buy an Allegro A sensor.
