Customer question on output amplifier impedance.
Q: Customer needs to know the status of EAR/HSO/PreDriv when they are not enabled. Is it high-impedance? Is there any condition we can put these output ports in high-impedance?
A: These output will be driven by a weak VMID signal. However, when these are not enabled these will be in high impedance state (actual impedance will be 1Mohm).
