RE: AD9613 Vcm max. load

Q

Can you tell me the maximum output current and minimum load impedance for the
AD9613 VCM pin?

A

The Vcm pin is capable of roughly driving up to 1.5mA, it is a very low current
pin. We would recommend only driving an amplifier with the Vcm voltage. The
basic idea is that the Vcm pin should only be used to set the common mode
voltage to whatever is driving the ADC inputs.
