Hi all, I want design 0-10 V transmitter card for use with load cell. And ı don't choice op-amp . Someone help me ?
Apologies for the late reply. You may consider using an in-amp for your application, to begin with you may use AD8422. Also we have Diamond Plot Tool to play around with your parameters to get a list of recommended amplifiers. You may also want read A Designer's Guide to Instrumentation Amplifiers (3rd Edition) | Analog Devices to help you with the use of In-Amps.
We have a dedicated page regarding your application for further information. The link is below:http://www.analog.com/en/applications/markets/instrumentation-and-measurement/weigh-scales.html
I am sorry for the late reply. Did you manage to get a suitable load cell amplifier for your system?
You have not provided specifications for your design but I will try to help using the little information that you have given us. However, I will not be specific since you have not specified how you are planning to configure your system.
To start with, when choosing a load cell amplifier for your design, it is important to have the requirements of the system that you are designing. These specifications will enable you to narrow down your search.
The key parameters that you should consider when selecting an op-amp for your design include voltage range, open loop gain, bias current, quiescent current, common-mode rejection, drift, and off-set voltage. For high precision and excellent performance, it is advisable to select an operational amplifier that offers ultralow offset voltage, high open loop gain, high power supply rejection, ultralow drift, high common mode rejection, low bias current, and low quiescent current. It is also important to consider your loading conditions when selecting an op-amp for your design.
From the details you have provided, a precision operational amplifier is a suitable option for your system. However, to simplify your design, it is better to use an integrated amplifier. Below is a link to load cell amplifiers that you can use for your design:
