Hi Nigel,
I think that you could try the next alternatives. You can use TAS2552's digital audio input instead of PCM1789 or you can connect the PCM1789 to TAS2552's analog audio input.
Please let me know your thoughts.
Best Regards
José Luis…
Hi Domenico,
The PCM1753-Q1 and PCM1789-Q1 both support this sample rate in a 4-wire configuration.
In regards to the clock tolerances, yes that is in both configurations. As the PCM510xA is a HW controlled device, it must auto-detect the input clocks…

Part Number: TAS5411-Q1 Other Parts Discussed in Thread: TINA-TI , PCM1789 Hi ,
We are using TAS5411QPWP Audio amplifier in one of our design. we have completed the schematic design for it .
We reviewed it at our end but looking forward for TI to review…
Hi Shawn,
Apologies for that , here are a few configurations appreciate your comments and advise on each, configuration 1 which shows Single ended buffered outputs of the PCM going into both channels of the TPA3132D2 with the one side of the AMP diff input…
So, TPA6138 can act as both LPF and amplifier simultaneously? no need for separate LPF?
Also the output of PCM1789 is 4Vpp centered at 2.5V while the input to the TPA6138 is 0V to 3.3V, so do i need to attenuate input signal to TPA6138? my attached schematic…
Hi CJ,
Thanks for the update and explanation. I think there is a sigma-delta DAC in front of the audio amplifier in your application, right? It use noise-shaping techniques to improve in-band SNR performance at the expense of generating increased out…
Other Parts Discussed in Thread: PCM1789 , DIR9001 , PCM1794A , DRV603 , OPA1612 , PCM1794 Hello,
is there anywhere explanation how to interface those three devices?
I was reading something( ) about interfacing DIR9001 and DRV603 with PCM1789, but PCM1789 seems…
