ADS1672 sampling rate

Other Parts Discussed in Thread: ADS1672

In the ADS1672 ADC. In looking through all available app-notes and data sheets, I was unable to find the lowest sample rate that the part will run at when using the Wide-Bandwidth filter path. Can you please provide this information?

Hello,

In the ADS1672 datasheet, page 14, in Table 2, you can find the lowest sample rate for 20MHz (which is 78.1kSPS).

Figure 19, page 12, shows that 2.5MHz clock is the slowest clock that we've tested/characterized the device with.

So, given the factor for 20MHz, the data rate for 2.5MHz is 9.76kSPS. Hope this clears it up for you.

Regards,

Michael

This last post was over 2 years ago. Has TI characterized the ADS1672 below 2.5 MHz sample clock rate since then or is 2.5 MHz still the minimum clock rate?

Thanks,

Tobyn

Mr VanVeghten -

The data in the datasheet is still valid.
