General Description

The Supertex HV254 is a 32-channel, high voltage, amplier

array integrated circuit. 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 amplier 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.

Operating Conditions

Absolute Maximum Ratings

Absolute Maximum Ratings are those values beyond which damage to the

device may occur. Functional operation under these conditions is not implied.

Continuous operation of the device at the absolute rating level may affect

device reliability. All voltages are referenced to device ground.

Power Up/Down Sequence

External Diode Protection

The device can be damaged due to improper power up/down

sequence. To prevent damage, please follow the acceptable

power up/down sequences and add two external diodes as

shown in the diagram below. The rst 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.
