INA301: Pull-up Resistor

Brian Wang0928

Part Number: INA301

In the d/s, it recommends 10K-Ohm for pull-up resistor. Is the 4.7KOhm or 6.8KOhm ok? how is the current sinking capability?

Regards

Hello Brian,

Thanks for reaching out on the forum. We dont provide a specification for the max drive current from the comparator. However, we do have a "Alert low-level output voltage" specification with a test condition of IOL = 3 mA. If I presume this is the max sinking current level, then I could have a resistance as little as (Vcc-Vol)/0.003A=(5V-0.07V)/0.003A=1643kohm.
