Hello, Hari,

What's the application that you are working on?

I recommend change you ADDR pull up to match the PU resistors on the SDA/SCL lines.

Please ensure that your enable signal timing will be able to meet t_en in the datasheet. Refer to section 7.4.1 in the datasheet.

Thanks,

Zach

Hi Zach,

This is used for display in our electric bike(Instrumentation Cluster)

I changed the resistor please see the below image.

I grounded the REFCLK using a 100K .Hope that is fine.

Hari,

Good starting place to tune if needed for the enable pin.

Thanks,

Hari,

Per the Hardware implementation guide, that is correct. The hardware implementation guide uses a 4.7k ohm as an example. You just need a Pull down resistor to GND if not in use.

Thanks,

Zach
