PA08 - 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

PA08 Frequently Asked Questions (FAQs)

  • Apex recommends a 2-layer PCB with a solid ground plane on the bottom layer and a thermal relief pattern on the top layer to ensure optimal thermal performance.
  • Apex recommends using external overvoltage protection (OVP) and overcurrent protection (OCP) circuits to prevent damage to the PA08. A fuse or a current-limiting resistor can be used for OCP, and a zener diode or a voltage regulator can be used for OVP.
  • Apex recommends using a 10uF to 22uF input capacitor and a 10uF to 47uF output capacitor to ensure stable operation and minimize noise.
  • Apex recommends using a voltage divider network to set the bias voltage, and ensuring that the bias voltage is within the recommended range of 1.2V to 3.5V.
  • The PA08 is rated for operation from -40°C to 125°C, but Apex recommends derating the output power by 1.5% per degree Celsius above 85°C to ensure reliable operation.
