HV254

32-Channel High Voltage

Ampliﬁer Array

Features

General Description

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.

► 32 independent high voltage ampliﬁers

► Up to 250V output voltage

► 3.0V/µs typical output slew rate

► Very low operating current (typically 45µA per

channel)

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 3V/µs. The internal closed loop gain is set at a

nominal value of 34.0dB (50V/V).

► High value internal feedback resistors

► Fixed gain of 50V/V

► Integrated silicon diode for temperature sensing

Applications

► MEMS (microelectromechanical systems) driver

► Piezoelectric transducer driver

► Optical crosspoint switches (using MEMS

technology)

The HV254 is designed to operate with minimal power

consumption 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.
