PA82J - Apex Microtechnology

Description: The PA81J and PA82J are high voltage power operational amplifiers that provide a wide range of supply capability. The PA81J is a 200V supply, 30mA output device, and the PA82J is a 300V supply, 15mA version. High accuracy is achieved with a cascode input circuit configuration. Target applications for these devices include high impedance buffers, electrostatic transducers and deflection, and programmable power supplies. These hybrid-designed products are housed in an electrically isolated, hermetically seal

PA82J Frequently Asked Questions (FAQs)

  • Apex Microtechnology recommends a 4-layer PCB with a solid ground plane, and thermal vias under the package to ensure efficient heat dissipation. A minimum of 2 oz copper thickness is recommended for the top and bottom layers.
  • Implement overvoltage protection (OVP) and overcurrent protection (OCP) circuits to prevent damage to the device. Apex recommends using a voltage clamp or a zener diode for OVP, and a current sense resistor with a comparator for OCP.
  • The PA82J is designed for a 50 ohm input and output impedance. Apex recommends using a conjugate match at the input and output to ensure maximum power transfer and minimum reflections.
  • Use a shielded enclosure, and ensure proper grounding and decoupling of the device. Apex recommends following good PCB design practices, such as separating analog and digital grounds, and using EMI filters or ferrite beads on input and output lines.
  • The PA82J is rated for operation from -40°C to +85°C. However, Apex recommends derating the device's power output and operating temperature to ensure reliable operation and extend its lifespan.
