TPA6211A1: Audio amp and codec

Part Number: TPA6211A1
Other Parts Discussed in Thread: LM4990

Tool/software:

Hi,

I'm looking for an audio amplifier to drive a single-ended 2W speaker with a frequency response that extends to at least 21.5kHz. Specifically, I need:

An I2S/PCM A/B amplifier.
If an I2S-capable amplifier isn't available, could you recommend an I2S/PCM audio codec to pair with the analog A/B amplifier LM4990?

Thanks!

Jeff

Hi Jeff,

Class-AB with digital input is not supported in our portfolio. TPA6211A2 is another option for analog input and Class-AB, similar to LM4990 but fully differential.

Regarding the DAC, you can narrow down some options. if you pick TPA6211A2 you can look for a differential output DAC as well, otherwise a single-ended option would work for LM4990:
