TPA5051: TPA5051 at Fs : 8 kHz

sebastien castel

Part Number: TPA5051

Hello,

Does the TPA505x works at sampling frequency of 8 kHz ? the datasheet refers to 32 to 192 kHz but it is not 100% sure that 32 kHz is a minimum.

Thank you

Sebastien

Hi Sebastien,

It seems TPA5051 is only specified from 32kHz to 192kHz FS rates, even D/S Figure 12 in page 16 shows this same range.
Even if device would be able to operate at a lower FS rate, the performance may not follow the specification so it's not recommended.

Hello Ivan,

thank you for your answer.

i will probably try to use a sample rate converter (SRC419x).

Hi Sebastien,

That seems correct so you can keep using TPA5051 within its spec range.
