The Supertex HV256DB1 is a 32-Channel 295V amplifier array with a nominal gain of 72V/V. The purpose of the HV256DB1 is to provide a means to easily evaluate the Supertex HV256FG 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 board. There are 32 pads on the left side of the board for the input signals and 32 pads on the right for the outputs. Be sure to follow the power up/down sequence to avoid damaging the device.
