Analog input voltage of AD7091R

kshigemori281 on Dec 20, 2021

Hi,

I confirmed below sentence. AD7091R has internal reference that 2.5V. In that case, Is it true my awareness that Input voltage depend on VREF.

==

analog input signal never exceeds VREF or VDD by more than 300 mV

==

Best regards

Hi kshigemori281,

Looking into the ABS/MAX rating on Table 3 of the AD7091R datasheet. The analog input range must be within the -0.3 to Vref+0.3 range. Beyond this range will forward bias the protection…

Hi kshigemori281,

Looking into the ABS/MAX rating on Table 3 of the AD7091R datasheet. The analog input range must be within the -0.3 to Vref+0.3 range. Beyond this range will forward bias the protection diode as explained on page 13 Analog input section.
