INA207: Absolute max voltage for V+/-

Hirokazu Takahashi

Part Number: INA207

Dear Support team,

According to datasheet, in absolute maximum voltage of V+/- at common mode is defined as -18~80V. Is it non-relation with Vs condition, Vs=open or Vs=0V?
When V+/- has some voltage level at "Vs=0V" condition, will any leakage voltage appear at other pins?

Best Regards,
Hirokazu Takahashi

    Hello Hirokazu,

    Thanks for considering to use Texas Instruments.  The specification in the absolute maximum conditions table indicate the VCM voltage does not depend Vs.  Therefore, the -18-80V applies to both Vs=0V and Vs=open.

    As Vs=0V condition falls outside of the operating conditions specified in the datasheet, I need to check with our design engineers or do a bench test.  As such I will try to have an answer for you tomorrow morning.

    Hello Hirokazu,

    I did a bench test with VCC=GND=0V and VIN+=12V.  I measured the following voltages with a 3401a multimeter.
