Part Number: OPA205
Hi, help in comparing the OPA205A with the AD741SH. I am good with most of the comparison but when I get to comparing the CMRR of the AD741 (Fig 5 on datasheet) with the various CMRR tables on the OPA205 datasheet I get lost. How does the OPA205A stack up against the AD741SH on CMRR vs Frequency?
Mike,
The table will show worst case and typical DC CMRR performance for both the ADI device and the TI device. The opa205 is significantly better than AD741 for both typical and worst case CMRR.
The typical AC CMRR is covered by the curves. The OPA205 looks better vs frequency as well.
Let me know if there is anything else you want to look at.
best regards, Art
