PA07A - Apex Microtechnology

Description: The PA07 is a 5A, 100V power operational amplifier designed for motor, valve and actuator control. For optimum linearity, especially at low levels, the output stage of the PA07 is biased for Class A/B operation using a thermistor compensated base-emitter voltage multiplier circuit. A thermal shutoff circuit protects against overheating and minimizes heat sinking requirements for abnormal operating conditions. The PA07A is the A grade version providing enhance performance in the areas of offset voltage, off

PA07A Frequently Asked Questions (FAQs)

  • A good PCB layout for the PA07A involves keeping the input and output traces short and symmetrical, using a solid ground plane, and placing decoupling capacitors close to the device. A 4-layer PCB with a dedicated power plane and a solid ground plane is recommended.
  • To ensure stability, ensure that the output impedance is matched to the load, and the input impedance is matched to the source. Also, use a compensation capacitor (e.g., 10nF) between the output and the inverting input to prevent oscillations.
  • The maximum power dissipation for the PA07A is 2.5W. Ensure that the device is properly heat-sinked, and the ambient temperature is within the recommended operating range to prevent overheating.
  • Yes, the PA07A can be used as a unity-gain buffer. However, it's essential to ensure that the input impedance is matched to the source, and the output impedance is matched to the load to prevent signal degradation.
  • Use voltage clamps or transient voltage suppressors (TVS) to protect the PA07A from overvoltage. For ESD protection, use ESD diodes or ESD-protected ICs in the signal path. Ensure that the PCB design includes ESD protection measures, such as ESD-protection diodes and resistors.
