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.

Features
► 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)
► 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)
