HV256 is a 32-channel, high voltage, amplifier array integrated circuit. It operates on a single high voltage supply, up to 300V, and two low voltage supplies, VDD and VNN.The input voltage range is from 0 to 4.096V. The internal closed loop gain is 72V/V, giving an output voltage of 295V when 4.096V is applied. Input voltages of up to 5.0V can be applied, but will cause the output to saturate. The maximum output voltage swing is 5.0V below the VPP high voltage supply. The outputs can drive capacitive loads of up to 3000pF.The maximum output source and sink current can be adjusted by using two external resistors. An external RSOURCE resistor controls the maximum sourcing current and an external RSINK resistor controls the maximum sinking current. The current limit is approximately 12.5V divided by the external resistor value. The setting is common for all 32 outputs. A low voltage silicon junction diode is made available to help monitor the die temperature.
