INA333: INA333 single supply mode and output offset

Tool/software:

Hi team,

We are using INA33 instrumentation amplifier for our new project. We are using INA333 in single supply mode operation. We have connected V+ pin to 3.6V and V- pin to GND. SInce it is a single supply mode, Vref pin of INA333 is connected to 1.8V (Mid point of the supply). The TINA simulation imgae is provided below:

As per datasheet, there is an offset og 50mV at the output.

1. Is the way of connecting the supply and Vref for single supply mode correct?

2. Is it possible to nullify the 50mV offset from the output? If possible, how to do that?

3. For the single supply mode operation, what is the formula for the gain calculation?

4. What is the minimum differential input voltage an INA333 can read?

Thanks & Regards,
