HV257DB1, Demo Board is a 32-Channel 295V sample and hold amplifier array with a nominal gain of 72V/V. The purpose of the HV257DB1 is to provide a means to easily evaluate the HV257FG device. A high voltage supply, VPP, and two low voltage supplies, VDD and VNN, are required. These connections can be made via the J1 header provided on the top of the demo board. Connections to the logic control inputs and VSIG analog signal are on the bottom of the demo board. There are 32 pads on the right side of the board for the outputs. Please follow the power up/down sequence to avoid damaging the device
