ALLEGRO A1301 PDF

Tojale One of my friends recommended me to buy an Allegro A sensor. 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. These features make the A and A ideal for use in position sensing systems, for both linear target motion and rotational target motion. 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. A and A Datasheet.

The information included herein is believed to be accurate and reliable. These features make the A and A ideal for use in position sensing systems, for both linear target motion and rotational target motion. Are the results voltages or random numbers? There are no news items available for this product. Low-noise output Fast power-on time Ratiometric rail-to-rail output 4. If this is not your local representative, find your local sales rep here.

My results show me random numbers varying from to which repeat at regular intervals. Integrating the Hall circuit and the amplifier on a single chip minimizes many of the problems normally associated with low voltage level analog signals.

Hello I think you need to go back to the basics Have you looked at the data sheet for this device? Conversely, the application of a north polarity —B magnetic field, in the same orientation, proportionally decreases the output voltage from its quiescent value. Note that some of these devices need a load resistor on the output pin plus decoupling Vcc to GND They are pretty resistant to abuse getting it wired up incorrectlybut will only take so much.

Is there another way to wire the sensor? Please contact the Allegro Marketing department for additional information. This proportionality is specified as the magnetic sensitivity of the device and is defined as: I assumed that the differences were determined by me approaching and retracting the Neodymium magnet from the sensor. In the quiescent state no significant magnetic field: Two output sensitivity options are provided: The Allegro site suggests that this is an end of life device, so maybe not the best choice.

Click the image alleyro view larger. In reality, after modifying the sketch and adding an extra variable to read an unused slot, I realized that the results were similar in nature.

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.

Integrating the Hall sensing element and the amplifier on a single chip minimizes many of the problems normally associated with low voltage a analog signals.

My goal is to make a device that can be used to sense some metal approaching it. Ambient Temperature Device Sensitivity vs. Samples are no longer available. Do I have to process the raw data in order to get some better results? TOP 10 Related.

Ambient Temperature Device Sensitivity vs. Allegro MicroSystems — A and A Continuous-Time Ratiometric Linear Hall Effect Sensor ICs Linearity in percent is measured and defined as: 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.
