Question: What are the differences between the standard AD712-4/8 and the B-grade
Answer: There are some key differences between the B-Grade (AD7124-xBBCPZ/AD7124-xBBCPZ-RL) and the standard (AD7124-xBCPZ/AD7124-xBCPZ-RL) AD7124-4/8. Choice will depend on your application requirements, here are the key differences between the two types
Multichannel settling time (at G=1):
Excitation currents status in standby mode:
Gain Registers value when MCLK & SCLK are Asynchronous
Question: Is the B-grade better than the standard AD7124-4/8.
Answer: Yes, the B-grade is better than the standard - for full details on the differences see above.
Question: Should I use the standard silicon or the B-grade
Answer: Yes for any new design the B-grade is recommended, for full details on the differences see above.
Question: How can I tell that the model part is a standard silicon or B-grade?
Answer: 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 above.
