Analog Devices Inc. EVAL-ADuM7811 Evaluation Board
Analog Devices EV-ADuM7811-8FMCZ Evaluation Board is a fully featured platform for evaluating the ADuM7811 isolated ADC with sigma-delta-modulated bitstream output. The board simplifies device assessment with on-board power supplies, SMA signal connections, test points for measurement, and standalone capability for flexible bench evaluation.
On-board ADuM6028-5 isoPower® DC-to-DC conversion, ADP7104 low-noise regulation, and ADP7142 low-noise CMOS LDO regulation support multiple supply configurations. The ADI EV-ADuM7811-8FMCZ Evaluation Board also supports PC-based control and data analysis via ACE Software. The board can operate in standalone mode or in a ZedBoard-controlled setup, depending on the link configuration.
