A high voltage operation amplifier (HVOPA) is an operational amplifier that can operate with input and output voltages ranging from tens to hundreds of volts. They are used when dealing with voltage ranges that cannot be covered by standard operational amplifiers.
When used, they must be properly designed, including protection circuits, in consideration of regulations and safety associated with high voltages. Heat dissipation design and thermal protection are also important because of the heat generated by the high currents in some cases.
High voltage operation amplifiers are an option for applications where the operating voltage range of standard operational amplifiers is not sufficient to handle the high voltages involved.
Examples include piezo transducers used in inkjet printers and ultrasonic transducers, automated test equipment for testing other ICs and modules, and high-brightness laser diodes used in optical detection and ranging systems. high voltage operation amplifiers are used in these applications.
High voltage operation amplifiers operate essentially the same as standard operational amplifiers, amplifying the potential difference between the inverting and non-inverting inputs with a very high gain. They can be used in the same way as standard op amps, with high input impedance, low output impedance, and an imaginary short between the two input terminals.
To accommodate a higher voltage range, a standard op amp can be combined with external components to boost the output voltage. However, the circuit is complex and costly, there are many components and board layout restrictions, and the output is affected by variations in component characteristics and board layout, resulting in distortion of the output and worsening linearity.
The use of high voltage operation amplifiers solves these problems. Some ICs also include ESD protection circuits, boost circuits to increase slew rate, circuits to drive capacitive and inductive loads stably, and thermal and overcurrent protection circuits in a single IC package, making design easier.
