I want you to give us advice.
OP2177 is targetted to be replaced with competitors, OPA2180 and so on.
We try to promote ADA4077-2A. But they mentioned TCVos is worse than OP2177. They don't want to use it.
ADA4522-2 doen't seem to compete with OPA2180 bacause of pricing.
Their requirement is as below,
Pin compatible with OP2177ARMZ
MSOP: We can't promote ADA4077-2B because ADA4077-2B is only available with SO-8.
Better TCVos MAX
Power supply: +/-15V
Input signal frequency: 50kHz
Cheaper than OP2177
Ta: -5'C to 85'C Actual Ta would be up to 60'C If we can guarantee ADA4077-2A is better TCVos than OP2177 at this temp range, we may keep this biz.
Cload: 0.1uF capability
