Posting on behave of a customer-
Customer has different modes of operation and they dynamically adjust the MUX power supply rails depending on the maximum signal expected at the inputs of the MUX.
Logic inputs are always 0 to +5 V there are 2 conditions which cause them to ask is this allowed:
Condition 1
MUX +PS = +6 V
MUX-PS = -30V
max swing of input analog signal to -27.5V
and condition 2
MUX + PS = + 35.5 V
MUX -PS = -0.5 V
max swing of input analog signal to + 33 V
Can you confirm these are allowed ( or dis-allowed ) conditions?
