PA91 - Apex Microtechnology

Description: The PA91 is a 450V power operational amplifier that exhibits a low 10mA of quiescent current and is designed as a low-cost solution for driving continuous output currents up to 200mA and pulse currents up to 350mA in high voltage applications including instrumentation, piezoelectric transducers and electrostatic transducers and deflection. External compensation with the PA91 provides flexibility in choosing bandwidth and slew rate for the application. Housed in a space saving, electrically isolated 12-pin P

PA91 Frequently Asked Questions (FAQs)

  • Apex Microtechnology recommends a 4-layer PCB with a dedicated thermal plane, and a thermal pad on the bottom of the package for heat dissipation. A thermal interface material (TIM) is also recommended to improve heat transfer.
  • Apex Microtechnology recommends using external protection devices such as TVS diodes and current limiting resistors to protect the PA91 from overvoltage and overcurrent conditions.
  • The recommended input impedance is 50 ohms, and the recommended output impedance is 50 ohms or lower. Impedance matching networks may be required to achieve optimal performance.
  • Apex Microtechnology recommends using a high-frequency layout, minimizing parasitic inductance and capacitance, and using a low-loss substrate material. Additionally, optimizing the input and output matching networks for high-frequency operation can improve performance.
  • Apex Microtechnology provides reliability data and MTBF calculations based on industry-standard models. Contact Apex Microtechnology for specific reliability data and MTBF calculations for the PA91.
