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) GENERAL DESCRIPTION
The Supertex 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.
