QUICK INITIAL HARDWARE SETUP AND OUTPUT
VERIFICATION
For an initial hardware setup and output verification, follow
these steps:
1. Connect the evaluation board to the SDP board, which
connects to the USB port of your PC system using a USB
mini-B cable.
2. Position manual switches to V
3. Jumper the VCLAMP connector pin to the VDD
connector pin.

4. Apply 10 mV dc signal between the +V
connectors, and monitor the V
voltmeter.
5. Place an AD8555/AD8556/AD8557
SOIC/LFCSP socket, connect the VCLAMP pin to the
VDD pin, and apply dc power to the board using an
external power supply (±2.5 V).
When this procedure is complete, the output is 70 mV, with the
board in this configuration consuming approximately 4 mA.
