I read Datasheet Rev.C.I have a question.
Is there red arrowy resistance for IB?Or is it here only for a termination?
It's usually unnecessary, but would this resistor be necessary for return from a power down mode?
When output was high impedance, I'm uneasy about a bias's functioning.
In a power down mode, how is the common voltage decided to middle electric potential?Is the resistor of a red arrow necessary then?Or is the connection with the simple capacitor enough?
I'd appreciate it if you could answer my questions.
I suspected my issue was related to the input bias of the AD8390A.However, the problem was another part.The problem was solved. Sorry to trouble you.
