Recommend INA for load cell

Other Parts Discussed in Thread: INA333

I have a 6kg load cell please suggest a suitable instrumentation amplifier so that I could connect to my microcontroller which have 16-bit ADC.

I am using a 6 kg load cell. And it is used to measure weight.

Also, I need 1 gram precision for this load cell.

Hello Naveen,

This got placed in the Current sensing because we use the INA part designator as well. I am moving this to the correct group.

Naveen,

Some extra detail is needed to provide a better recommendation. What power supply voltage are you using? What is the span of the sensor in mV/V? What is the minimum level you need to resolve? What is the ADC input range? What sampling rate do you plan on using.

Assuming a 5V supply, one common choice is INA333.

Best regards,

Art
