Original question:
TLV2241: I am looking the best opamp that fits my requirements
I am looking for an opamp with a +/- 3V supply voltage, low Vos offset voltage and comes in a both a small package option for production and also a SOIC package option for easy prototyping. Is the OPA171 the best opamp for these requirements?
I really appreciate the help with this.
Hey John,
Welcome to e2e!
I think the best course of action is to prototype with a dual op amp (more are available in SOIC) and design in a single op amp (available in smaller packages).
It is inefficient to design a single channel 8 pin SOIC so the newer devices do not come in this package option; luckily, the quad/dual/single within a family are all the same just in different packages.
Here is a parametric search showing dual op amps that have SOIC packages, filtered by the most package options, and 6V rail.
I recommend the top 6 options as these are our newer devices: TLV9102, TLV9152, TLV9162, OPA2990, OPA2991, and OPA2992.
As you can see, looking at the OPAx991 datasheet, that the dual is available in SOIC 8 and the single is available in the tiny SC70.
In the prototyping, I imagine one of the channels will remain unused, I recommend following the guidelines in How to Properly Configure Unused Operational Amplifiers
All the best,
Carolina
