PA08A - Apex Microtechnology

Description: The PA08 is a high voltage power operational amplifier designed for output voltage swings up to ±145V with a dual supply, or a 290V single supply. This power amplifier delivers high accuracy via a cascode input circuit configuration. All internal biasing is referenced to a zener diode fed by a FET constant current source. As a result, the PA08 features an unprecedented supply range and excellent supply rejection. Target applications for this POA include electrostatic transducers, deflection circuits and pro

PA08A Frequently Asked Questions (FAQs)

  • Apex Microtechnology recommends a 4-layer PCB with a solid ground plane, and thermal vias under the package to dissipate heat. A heat sink or thermal pad can also be used to improve thermal management.
  • To ensure reliable operation at high temperatures, Apex recommends derating the output current and voltage, and using a heat sink or thermal pad to keep the junction temperature below 150°C. Additionally, using a thermally conductive material for the PCB and ensuring good airflow can help.
  • The maximum safe operating area (SOA) for the PA08A is not explicitly stated in the datasheet. However, Apex recommends limiting the output current to 8A and voltage to 80V to ensure reliable operation. Exceeding these limits can lead to device damage or failure.
  • Apex recommends using external protection circuits, such as overvoltage protection (OVP) and overcurrent protection (OCP) circuits, to prevent damage to the PA08A. Additionally, using a fuse or current-limiting resistor can help protect the device from overcurrent conditions.
  • Apex recommends storing the PA08A in a dry, cool place, away from direct sunlight and moisture. The device should be handled with anti-static precautions, such as using an anti-static wrist strap or mat, to prevent electrostatic discharge (ESD) damage.
