This user guide describes the EVAL-ADHV4702-1CPZ board, which helps users evaluate the ADHV4702-1 offered in a 7 mm × 7 mm, 12-lead lead frame chip scale package (LFCSP) with an exposed pad at the bottom. The evaluation board provides a platform for quick and easy evaluation of the ADHV4702-1. Figure 1 in the user guide shows the top side of the evaluation board. Figure 2 shows the bottom side of the board with the large exposed copper area for attaching a heat sink to provide additional thermal management.
The evaluation board is a 6-layer board designed to minimize leakage currents with its guard ring feature. It accepts Subminiature Version A (SMA) and Subminiature Version B (SMB) edge mounted connectors on the inputs for easy connection to test equipment or other circuitry.
Full specifications of the ADHV4702-1 and details of the device operation and application circuit configurations and guidance can be found in the ADHV4702-1 data sheet, available from Analog Devices, Inc., and must be consulted in conjunction with the user guide, especially when powering up the evaluation board for the first time.
For safety, the EVAL-ADHV4702-1CPZ board is covered top and bottom with acrylic plastic guards to reduce the risk of inadvertent contact with high voltage. Do not operate the board without these guards in place. If the guards must be removed to adjust jumpers or change component values, disconnect the board from the power supply before removing guards, and replace the guards before powering up again.
Warning: this high voltage evaluation board contains exposed metal carrying lethal voltages when under power. Take all necessary steps to protect users during operation. For full precautions when using this high voltage evaluation board, see the High Voltage Evaluation Board section of the user guide.
