Other Parts Discussed in Thread: TPA6120A2, OPA1622

Hi, TI Audio Team.

I am looking for a Audio Amplifier IC which can support 100mW@300ohm as a output power.

Would you let me know the proper Audio Amplifier IC?

If there is no IC can support 100mW@300ohm, would you share circuit which can support 100mW@300ohm?

I really need your help.

thank you.

    Hi Jae,

    TPA6120A2 and OPA1622 are a couple of amplifiers usually tagged for this kind of higher impedance headphone applications.

    TPA6120A2 has EVM available for both package types, and OPA1622 also has EVM as well as Spice models so you can evaluate your specific application.
