Hello!

Would TPA6211A1 work correct with 600 Ohm load resistance?

Thank you.

Hi Vladislav,

The TPA6211A1 can work with load resistance higher than 3 Ω. But, I consider that the output power will be very low with a 600 Ω load resistance.
Could you provide more details about your application?

Hello Jose Luis, thank you for answer,
in the technical requirements of my device, audio output is headphone with 600 Ohm impedance. I think i can just connect audio codec (CS4244) to connector thru LPF, but i want some buffer, and may be my customer change her mind, and want more powerful output.

Hi Vladislav,

This device isn't designed to work with Headphones.
I consider that TPA6120A2 fits in your applications due to this device is used with high output impedance or you could have a look at the product folder of our Headphone Amplifiers.

Please let me know your comments.
