PA78DK is a high-voltage, high-speed power op amp for pulse, piezoelectric, and electrostatic-drive circuits requiring up to 150 mA continuous output current.

Best for

  • High-voltage pulse amplification
  • Piezoelectric positioning and actuation
  • Electrostatic deflection drive
  • Capacitive-load drive with controlled compensation

Avoid if

  • The design cannot provide external compensation components
  • The output load can exceed the SOA or thermal capability
  • A low-voltage general-purpose op amp is sufficient

Check before use

  • 350 V total supply-voltage limit
  • 150 mA continuous and 200 mA peak output-current limits
  • Output voltage swing at required load current
  • Compensation, bypassing, layout, and heatsink performance
