It operates on a 275V high voltage supply and two low voltage supplies: +5.0V and -5.0V. Each channel has its own input and output. An integrated diode is included to help monitor die temperature. The input voltage can be from a DAC (Digital to Analog Converter) with a voltage range of 0V to the low voltage supply, V+. The output of the HV254 will swing from 7.0 to 250V. It cannot swing to ground. With the internal gain set at 50V/V, a minimum input signal of 140mV will still maintain linearity. Input voltages below 140mV can be applied without damage to the device. However, the amplifier will be saturated. Typical output load is equivalent to a 125MΩ resistor in parallel with a 100pF capacitor. The outputs have a guaranteed slew rate of at least 3.0V/µs. The internal closed loop gain is set at a nominal value of 34.0dB (50V/V). The HV254 is designed to operate with minimal power consumption while maintaining a guaranteed slew rate of 3.0V/µs. High value resistors are used for the gain setting to minimize current on the feedback path.

To prevent damage, please follow the acceptable power up/down sequences and add two external diodes as shown in the diagram below. The first diode is a high voltage diode across VPP and V+ where the anode of the diode is connected to V+ and the cathode of the diode is connected to VPP. Any low current high voltage diode such as a 1N4004 will be adequate. The second diode is a schottky diode across V- and DGND where the anode of the schottky diode is connected to V- and the cathode is connected to DGND. Any low current schottky diode such as a 1N5817 will be adequate.
