For the AD55xx family of I-Out DACs what is the maximum voltage allowed as a bias voltage on Iout2 pin?
Most of the AD55xx Iout DACs are not suitable to be used with IOUT2 (AGND) biased above ground.
For AD5555, the highest voltage that you can raise on the AGND pin 0.5V provided VDD is 5V and is very stable.
