Part Number: ADS8638
Other Parts Discussed in Thread: ADS8634

Hi,

- Can you please clarify if the AL_PD pin has a weak pull-up when set as input, for both ADS8634 and ADS8638 devices?

The datasheet suggest on page 8 that ADS8634 has that, but page 9 suggest that ADS8638 has not a weak pull-up.

Thanks for checking this for us.

M.A.M,
When programmed as power-down input pin, AL_PD pin has weak pull-up resistor on both ADS8634 and ADS8638 devices. Sorry about the confusion on Page 9.
Thanks,
Vishy
