ADC121S021: For 16V application

Hi Tom,

Does there have reference design can share to us?

Thanks!

Jeff

I don't have anything handy, let me look around.

Hi Tom.

Is it advisable to use ADC121S021 for voltage division of 16V using resistors? Can it achieve an accuracy of 0.1V? Thanks!

Jeff

Hi Tom,

So no need any buffer, just using resistive divider is fine? I saw you mentioned using a buffer to feed the input. thanks!

If you are looking for more than 100mV of resolution, you might need a buffer.  I suspect you would get what you are looking for without a buffer.

Hi Tom,

You mean if I just achieve an accuracy of 0.1V, it no need any buffer, just using a divide resistor if fine? thanks!

I don't think you will need a buffer.
