LDC1312: SD pin

Hirotaka Matsumoto

Part Number: LDC1312

Hi all

Would you mind if we ask LDC1312?
In order to enter shut down mode, how much is the time which SD input must be held high?

Because, our customer would like to know the minimum time which is from SD high input to transition to I2C readback.

On the datasheet only shows "Wake-up Time from SD high-low transition to I2C readback".
So, we think that our customer requires "tWAKEUP" + "the time which SD input must be held high".

Kind regards,

Hi Hirot,

The time that SD needs to stay high for should be negligible compared to that of tWAKEUP.

Thank you so much for your reply.

->OK, does it mean that SD High 100us is enough time, right?

We need your help.

Kind regards,

Hi Hirotaka-san,

100us should be good enough.

Best,
