General Description

V-

The Supertex HV254 is a 32-channel high voltage amplifier

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.

swing from 7V to 250V. It cannot swing to ground. With the

internalgainsetat50V/V, aminimuminputsignalof140mVwill

still maintain linearity. Input voltages below 140mV can be

applied without damage to the device.The amplifier, however,

The HV254 is designed to operate with minimal power con-

sumption while maintaining a guaranteed slew rate of 3V/µs.

High value resistors are used for the gain setting to minimize

current on the feedback path.
