| The [[ADI>AD8212]] is a high common-mode voltage, current shunt monitor. It accurately amplifies a small differential input voltage in the presence of large common-mode voltages up to 65 V (>500 V with an external PNP transistor). The [[ADI>AD8605]] is a single rail-to-rail input and output, single-supply amplifier. It features very low offset voltage, low input voltage and current noise, and wide signal bandwidth. | The [[ADI>AD8212]] is a high common-mode voltage, current shunt monitor.

| The [[ADI>ADuM5402]] is a quad channel isolator that provides galvanic isolation for the circuit. This is not only for protection but to isolate the downstream circuitry from the high common-mode voltage. In addition to isolating the output data, the digital isolator can also supply isolated +3.3 V for the circuit. | [[ADI>ADuM5402]] is a quad channel isolator that provides galvanic isolation for the circuit.

| | |
| | - Connect the 120-pin connector on the [[adi>EVAL-CN0218-SDPZ|EVAL-CN0218-SDPZ Evaluation Board]] to the connector marked “CON A” on the [[adi>EVAL-SDP-CB1Z|EVAL-SDP-CB1Z]] evaluation (SDP) board |
| | - Connect a shunt resistor across the input terminals with a load to ground as indicated in figure above |
| | - With power to the supply off, connect a +6 V power supply to the pins marked “+6V” and “GND” on the board |
| | *//If available, a +6 V "wall wart" can be connected to the barrel connector on the board and used in place of the +6 V power supply// |
| | - Connect the USB cable supplied with the SDP board to the USB port on the PC |
| | - Apply power to the +6 V supply (or “wall wart”) connected to [[adi>EVAL-CN0218-SDPZ|EVAL-CN0218-SDPZ Evaluation Board]] |
| | - Launch the evaluation software |
| | - Connect the USB cable from the PC to the USB mini connector on the SDP board |
