INA194A-Q1: Analog Inputs, Vin+ Vin- maximum value

Ulrike Behringer

Part Number: INA194A-Q1
Other Parts Discussed in Thread: INA194

hi there,

my customer wonders which maximum values for the Analog Inputs, Vin+ Vin- on INA194A-Q1 apply. the datasheet of INA194 lines out -18 to +18V ; in the datasheet of INA194A-Q1 this line is missing. here it is only mentioned the common mode voltage and the differential voltage.

please help to clarify.

thanks, Ulrike

Hi Ulrike,

seems to be a mistake in the datasheet:

Hello Ulrike,

Thanks for reaching out on the forum. As Kai pointed out, the analog inputs line is ambiguous and a mistake. Your customer will need to observe the conditions outlined by the differential voltage (potential between IN+ and IN-) and the common mode voltage (potential between gnd and the average sense pin voltage, ~=IN-).
