Hello user3830479,
To replace the AD8667, check our OPA2187. OPA2187 is a Zero-Drift(check out the tech note here: http://www.ti.com/lit/an/sbot037a/sbot037a.pdf ) wide supply CMOS OpAmp that easily goes head to head with the competitive device and dominates in all areas. Please see the spec comparison below and feel free to order some free samples from ti.com/product/OPA2187
Best regards,
Raphael Puzio

Hi,
I was trying to keep the IQ down. The IQ of OPA2197 is 10X that of OPA2187 which is 5X that of LMC6482 and AD8667. If you're going with a device like this, go with the OPA2196 as the IQ is lower and the cost is even more competitive.
