Please contact the Allegro Marketing department for additional information.
Low-noise output Fast power-on time Ratiometric rail-to-rail output 4. The A and A feature a ratiometric output.
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. Hello I think allwgro need to go back to the basics Have you looked at the data sheet for this device? What do you mean by “slot”? This proportionality is specified as the magnetic sensitivity of the device and is defined as: Two output sensitivity options are provided: For the latest version of this document, visit our website: High precision in output levels is obtained by internal gain and offset trim adjustments made at end-of-line during the manufacturing process.
Allegro A1301 SIP-3 Hall-effect sensor 2.5mV/G
Integrating the Hall circuit and the amplifier on a single chip minimizes many of the problems normally associated with low voltage level analog signals. The on-chip output stage is designed to provide linear output at a supply voltage of 5 V. Two output sensitivity options are provided: One of my friends recommended s1301 to buy an Allegro A sensor. Before placing an order, the user is cautioned to verify that the information being relied upon is current.

There are no news items available for this product. Allegro are generally pretty good at application notes, so I would start there, before even starting with code.
Alleggro the quiescent state no significant magnetic field: Two device package types are available: Read the data sheet.
Although the application of very high magnetic fields does not damage these devices, it does force their output into a nonlinear region.
Conversely, the application of a north polarity —B magnetic field, in the same orientation, proportionally decreases the output voltage from its quiescent value.
A1301 and A1302: Continuous-Time Ratiometric Linear Hall Effect Sensor ICs
Is there another way to wire the sensor? You say you want to detect “metal” 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.
However, Allegro MicroSystems, Inc. These features make the A and A ideal for use in position sensing systems, for both linear target motion and rotational target motion.
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? A and A Datasheet. They are optimized to accurately provide a voltage output that is proportional to an applied magnetic field. This classification indicates that the product is obsolete and notice has been given.
Linearity in percent is measured and defined as: Sale of this device is currently restricted to existing customer applications.
Therefore I would like to ask the kind forum members the following questions: If yes, how can I test to find it out?
My goal is to make a device that can be used to sense some metal approaching it. Low-noise output Fast power-on time Ratiometric rail-to-rail output 4. 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. The device should not be purchased for new design applications because of obsolescence in the near future.
Allegro MicroSystems – A and A Continuous-Time Ratiometric Linear Hall Effect Sensor ICs
My results show me random numbers varying from to which repeat at regular intervals. Are the results allsgro or random numbers? 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. Units — — 4.
They are optimized to accurately provide a voltage output that is proportional to an applied magnetic field. The Allegro site suggests that this is an end of life device, so alletro not the best choice. 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.
Samples are no longer available. Ambient Temperature Sllegro Sensitivity vs. Do I have to process the raw data in order to get some better results? These features make the A and A ideal for use in position sensing alleggo, for both linear target motion and rotational target motion.
Thank you and have a nice week ahead!
