Other Parts Discussed in Thread: ADS4449, ADS58H40
I want to use 'ADS4449' to operating ad conversion for our system.
According to the datasheet, there are 3 voltage supply sources for the chip : 3.3V, 1.9V, and 1.8V.
In the schematic of 'ADS4449 EVM(ADS58H40 EVM)', however, only 2 voltage sources, 3.3V and 1.9V, are used.
Is it ok and is the circuit operating normally when I use only 2 voltage sources?
