Hello support team,
Could you provide equivalent circuit of the inputs (INP, INM) for LMH6401?
I just would like to know how the mid-supply voltage is determined internaly. Is there a resistor divider?
Thanks and regards,
Katsuhiko Kaizawa

Hello Kaizawa-san,
To protect customer information I am only providing TI content on E2E. I am posting the following in case someone else has the same question.
The input common mode of the LMH6401 is set by a resistor divider between the two supplies. It will track the mid supply voltage for any supply configuration. It is connected to the first element of the input attenuator as shown below.

Loren
