FAQ: What is the maximum achievable output signal swing of the ADG3123?
Answer:
In Table 1 of the specification of the ADG3123, it is stated that the maximum output peak to peak signal amplitudes of the ADG3123 is 35 V. This represents the difference between the maximum positive and negative output voltages.
As the power supply has a minimum value for the VDDB, the maximum positive and negative voltages cannot be achieved at the same time.
To achieve the maximum negative output voltage of 24.2 V (VSS = -24.2 V), the positive power supply needs to be set to the minimum value of +10.8 V while for the maximum positive output signal of 35 V (VDDB = 35 V), the negative supply (VSS) must be 0 V.
