Hi.. i'm looking for a signal conditioning CHIP for converting the output of a single point load cell of 2mV/V to 0~10v. this chip must consist of a low pass filter which is to remove the noise ( high freq) and an amplifier to amplify the signal from 2mV to the range of 0~10V.Do you have any idea on this kind of chip? can i have the s/n of this chip? Thanks
You need a bit more spec before you can decide how to process the signal. For load cell signal the key parameters are usually noise, offset drift over temperature and gain drift over temperature. Undemanding applications can get away with 'scale on a chip' solutions but good load cells outperform such chips.

You bring up a very good pooint. However, many people looking for load cell conditioning circuits or chips do not need all of the performance that the load cell will provide. I leave it to the user to decide if a given circuit or chip will provide the performance he/she needs. With the type of questions we have on this forum, there is generally no way to know all of the requirements any given person has. But your comment is a good one and I do appreciate it.
