A high voltage operation amplifier (HVOPA) is an operational amplifier capable of handling input and output voltages ranging from tens to hundreds of volts. They are utilized in scenarios where standard operational amplifiers are insufficient for managing high voltage ranges.
When deploying HVOPAs, it is crucial to design them with proper protection circuits, keeping in mind regulations and safety concerns associated with high voltages. Effective heat dissipation and thermal protection are also vital due to the potential for significant heat generation from high currents.
High voltage operation amplifiers are chosen for applications where the voltage ranges exceed the capabilities of standard operational amplifiers. They are commonly found in piezo transducers in inkjet printers and ultrasonic transducers, automated test equipment for ICs and modules, and high-brightness laser diodes in optical detection and ranging systems.
Functionally, HVOPAs operate similarly to standard operational amplifiers, amplifying the potential difference between the inverting and non-inverting inputs with high gain. They offer high input impedance, low output impedance, and the characteristic virtual short between input terminals.
To manage higher voltage ranges, standard op amps can be augmented with external components to increase output voltage, but this approach is complex and costly, involving numerous components and specific board layout considerations. This can lead to output distortion and reduced linearity due to variations in component characteristics and board layout.
The use of HVOPAs addresses these challenges. Some HVOPAs integrate ESD protection circuits, boost circuits for increased slew rate, circuits for stable capacitive and inductive load driving, and thermal and overcurrent protection circuits, all within a single IC package. This integration significantly simplifies the design process.
