PA194 High-Speed, Low-Noise Power Operational Amplifier

Apex Microtechnology’s PA194 is designed for applications where high voltage with fast rise and fall times and low noise is key

Image of Apex Microtechnology PA194 Op Amp Apex Microtechnology’s PA194 is the next addition to Apex’s high-speed, high-voltage line of linear operational amplifiers. The PA194 operates off a 900 V supply capable of up to 2100 V/µs slew rate, 30 W power dissipation, and low noise. It is designed for applications where high voltage with fast rise and fall times and low noise is key. The PA194 utilizes discrete components packaged in an 8-pin power SIP with metal head tab measuring just 57 mm x 30 mm. The PA194 also has an integrated standby mode with a low quiescent current of 4 mA which contributes to overall system efficiency.

Features
  • High slew rate: 2100 V/µs
  • High supply voltage operation: 900 V
  • Low noise density: 4 nV/√Hz @ 10 kHz
  • Output current: 100 mA continuous, 200 mA peak
  • Integrated standby mode
Applications
  • Focused ion beam equipment
  • Microscopes
  • Sonar systems
  • Lithography systems
  • Ultrasonic therapy and surgical tools
  • Vibration cancellation
  • Heads-up displays
  • Analysis equipment
  • Inspection systems
