We are having difficulties obtaining this part. Do you have a 'drop-in'
replacement for this part, with a similarly low input offset voltage, in a 8pin
DIL package. We are using this amplifier in a battery powered, portable,
analyser using electro-chemical sensors, and require a dual version of the
OP90/OP07 type amplifier.
We have availability on the OP290FZ and EZ grades. These are the CerDIP package
options but they will drop into a plastic DIP slot. Expect to pay more for the
cerDIP package though.
Other opamps to consider are the OP281GP which also meets your requirement of
lower power, dual, <500uV offset, <25nA bias.
