  • RE: LMV321: In the process of production, the IC LMV321 used for amplification function is 16% bad, and there will be noise.

    Clark, OPA314 is a good choice. I prefer TLV6741; reducing noise was a key factor in its design. R243 and C217 are set to 73kHz, if you need less bandwidth then C217 can be increased to reduce total noise level.
