Part Number: TIDA-00851-LDC0851 Other Parts Discussed in Thread: LDC0851 , LDC1612EVM , BOOST-LDC3114EVM , TIDA-00508 Hello Team,
I have gone through LDC0851 user guide , in that you have mention that only 32 position it can detect, can you elobrate…
Part Number: TIDA-00851-LDC0851 Other Parts Discussed in Thread: LDC0851 Dear sir,
I am planning to replace traditional proximity sensor discrete circuit with the chip LDC0851.
For coil design the recommended thickness for the PCB as well as copper…
Hello Yuhao,
This could be achieved with the LDC0851. Please see the reference design below. It is important to note that this design does not determine rotation direction(CW or CCW). In order to determine direction, you would need to have a 2nd LDC0851…
Ivano,
That makes sense for simplicity.
To determine direction, you would place the two sensors next to each other so that the rotating target goes over both sensors individually. With this setup, in clockwise direction, you would see one sensor 1…
Other Parts Discussed in Thread: TIDA-00851 , PGA900 I build the board based on TIDA-00851 design to measure RTD and testing it using PGA900EVM board. I am following all steps from the design guide but I am getting the negative voltage readings.
The…
Hello All,
The construction shown above will not work. The LDC sensor needs to have an unobstructed view towards the rotating metal. If you have other metal between the sensor and the moving target, the LDC will be unable to sense this. If there is…
Paul,
The LDC0851 has a switch type output that can be used for event counting. Here is an event counting reference design:

Depending on the mechanical design of the pulley, it might be more reliable to read…
This LDC0851 event counting TI design should help you get started:

You can also order an LDC0851 EVM so that you can start learning how it works and prototyping. The EVM features a break-away design so that you…
Hi Robert,
Please also refer to a similar application note using the LDC0851 to detect the rotational speed of a fan: www.ti.com/.../TIDA-00851-LDC0851
Does this sound like what you're looking for?
Thanks,
Luke
