TAS5720L: Support low sampling rate or not?

Stephen Chow

Part Number: TAS5720L

I am considering to use TAS5720L from my design. I can find that it supports 44.1kHz to 96kHz sampling rate from the data sheet but it is not clear that it can support the sampling rate below 44.1kHz or not.

Anybody know it can support the following sampling rate with 8bits and 16bits or not?

8k, 10.025k, 12k, 16k, 20.05k, 24k, 32k

Thanks a lot.

Hello Stephen! The TAS5720 has an associated Wiki that goes into much more detail at: e2e.ti.com/.../2425.i2s-clock-requirements-on-tas570x1x2x3x-device-s Please let me know if this helps you. Thanks, Jeff

Thanks Jeff. The information is very useful.

If it is 3 wire I2S operation without MCLK, does it still support auto detect at low sampling rate?

Hello Stephen! You are assuming TDM Interface and if so how many amp units are you trying to implement in the system? Normally you need to follow the guidelines of 7.3.3 Serial Audio Interface. Thanks, Jeff
