HV257DB2

The Supertex HV257DB2 is a 32-Channel, 295V, sample and hold amplifi er array with a nominal gain of 72V/V. The purpose of the HV257DB2 is to provide a means to easily evaluate the Supertex HV257FG device. A high voltage supply, V_PP, and four low voltage supplies, AV_DD and DV_DD, AV_NN and DV_NN, are required. Referring to the demo board drawing shown below, the logic and V_SIG connections are on the left, the high voltage outputs are on the bottom, and the supplies are on the right. Please follow the power up/down sequence to avoid damaging the device.
