TLV320ADC3140: Function restrictions depending on the clock frequency

Part Number: TLV320ADC3140

Hi,

I plan to use TLV320ADC3140 with Fs=8kHz, 3ch, 32bit.

Are there any functional restrictions such as some functions are not supported if the Fs is not high enough?

Thanks,

Koki

Hello Koki,

The information about which features are supported at which sampling rates can be found in great detail in the app note below:

For instance, as shown in Table 2, at 8kHz, only the low latency and linear phase filters are supported, not the ultra-low-latency filter.

Hi, Collin

Are there any restrictions on the operation when the PLL is disabled?

Hi Koki,

If the desired combination is not listed in the "PLL Disabled" section of the application note, then that mode of operation is not supported.
