Part Number: TLV2374-Q1

Customer is using TLV 2374-Q1.
Noise problems occurred in the EMI test and countermeasures are required.

Q1.
Could you give me some information and advice on recommended circuits and pattern information for this amplifier's noise countermeasure?


*Supplement
I contacted the customer with the following contents as information that can be provided.

1)TI E2E Community Analog Wire blog

2)The Unused Op Amp

Is any information other than these available?

    Harukawa-san,

    You have found a couple good resources links on EMI. I would also recommend that the customer take a look at the following:
    www.ti.com/.../szza009.pdf
    www.ti.com/.../sboa128a.pdf

    Can you provide more detail on what type of issues the customer is seeing? While the op-amp may have an impact on EMI there are also many system parameters to consider so seeing a schematic would be quite helpful. It is very difficult to diagnose without knowing what configuration the op-amp is being used in.

    Thank you,
    Paul
