Description

The PA78 is a high voltage, high speed Precision IC power op amp with performance and unique features not found previously in any commercially available OpAmp. Novel input stage design of PA78 provides extremely high slew rates in pulse applications while maintaining low quiescent current of under 1mA. This novel input stage also has the effect of adding variables to the power response and slew rate characteristics of PA78. To a lesser degree, there are also input related effects on unity gain bandwidth and phase. PA78 is important to note that the slew rate is a strong function of input voltage amplitude. PA78should be noted that the package tab needs to be connected to a stable reference such as GND for high slew rates. Please refer to special considerations section for details.

The output stages of PA78 are well protected with user defined current limit although the Safe Operating Area (SOA) must be observed for reliable protection. Proper heatsinking is required for maintaining maximum reliability. External phase compensation provides the user with great flexibility in trading gain, stability and bandwidth.

Applications:

  • Piezoelectric Positioning and Actuation
  • Electrostatic Deflection
  • Deformable Mirror Actuators
  • Chemical and Biological Stimulators


The PA69 is a high voltage, high speed Precision IC power op amp with performance and unique features not found previously in any commercially available OpAmp .

Novel input stage design of this amplifier provides extremely high slew rates in pulse applications while maintaining low quiescent current of under 1mA. PA78  input stage also has the effect of adding variables to the power response and slew rate characteristics of the amplifier. To a lesser degree, there are also input related effects on open loop gain and phase.PA78  is important to note that slew rate for the PA69 is independent of supply current. However the slew rate is a strong function of input voltage amplitude. PA78 should be noted that the package tab needs to be connected to a stable reference such as GND for high slew rates. Please refer to special considerations section for details.

The output stages of PA78 are well protected with user defined current limit although the Safe Operating Area (SOA) must be observed for reliable protection. Proper heatsinking is required for maintaining maximum reliability. External phase compensation provides the user of PA78 with great flexibility in trading gain, stability and bandwidth.
