TAS5634: Description & parametrics on website - Sampling Rate

Davide Ballo

Part Number: TAS5634
Other Parts Discussed in Thread: TAS5558,

Hello,

on the ti website, in the parameters section, a Sampling Rate (max) is reported.

What is releated to this parameter?

The suggested I2S to PWM (TAS5558) works with a 192kHz signal. There is a limitation for the I2S signal when the TAS5634 is connected to the TAS5558?

In the datasheet of TAS5634 there isn't any information about Sampling Rate.

Thanks.

Best Regards,

Davy

Davy,

We realized that these PWM input amps don't actually have an input sample rate parameter so that line will be removed from the TI.com parametric tables. Thanks for bringing this to out attention.

The 192kHz is the audio sample rate inside the TAS5558, the output of the TAS5558 is the ~384kHz PWM waveform. The TAS5558 is fully compatible with the TAS5634 and other PWM input amps.

Regards,

Thanks very much for your reply.

Indeed I couldn't relate the sampling rate to the PWM frequency.

Now everything is clear. Thanks very much.

Best Regards,

Davy
