Does ADA4950-1/2 power down pin have an internal PU or PD resistor ?
Datasheet does not mention this.
Have a nice day...
Did a dirty prototype..
PD pin has an internal pull up...
As datasheet does not mention about this,
is it safe to keep it disconnected for always on mode ?
ADA4950 is an active low amplifier. It is always safe to connect the PD pin to VCC (+Vs) for normal operation.
