Tool/software:

Hello team,

To reduce the BOM, are we able to open the OUTN pin as shown below?

In this case, is below correct?

IN voltage = 0V --> OUTP voltage = 1.44V typ
IN voltage =0.5V --> OUTP voltage = 1.44V＋0.25V=1.69V

Regards,

Hi Hirata,

What customer and application is this for?

You can use only the OUTP pin, but you should tie the OUTN pin to ground through a 10k resistor for best practice. The caveat to this would be that it sacrifices half of the full-scale range and there would not be filtering. Please let me know if I can answer any more questions, thank you.

Best regards,

Eva

Hi Eva-san,

Thanks for your answer. So you mean below is true, right?

IN voltage = 0V --> OUTP voltage = 1.44V typ
IN voltage =0.5V --> OUTP voltage = 1.44V＋0.25V=1.69V
