I'm confused with the power supply of AD9957 evaluation board. The following picture is the Power Connection part of the board.
As the UG-208 says, TB1 and TB2. TB1 powers the USB interface circuitry, the digital I/O interface, and the digital core. TB2 powers the DAC and the clock input circuitry.
- What if powering TB2 with analog voltage and analog GND?
- How much of the courrent?
Thanks very much!
