AD7124 FAQ: How can I tell that the model part is a standard silicon or B-grade?

When ordering there are two options available, AD7124-4BBCPZ/AD7124-8BBCPZ-RL and AD7124-4BCPZ/AD7124-8BCPZ-RL. The extra B in the first option represent the B-grade. The B-grade offers substantial improvement over the standard silicon and therefore would be recommended for new design, for full details on the differences see link below:
