40A Power Amplifier with High Internal Power Dissipation

  • High internal dissipation – 400W
  • High output current – 40A continuous, 80A PEAK
  • High slew rate – 50V/µs
  • Optional boost voltage inputs
Apex Microtechnology's PA52, a 40 A Power Amplifier with High Internal Power Dissipation

The PA52 is a 40A (80A PEAK), 200V power operational amplifier featuring 90kHz of power bandwidth and a 50V/µs slew rate. With this combination of high current output, bandwidth, slew rate, and 400 watts of internal power dissipation, the PA52 is targeted for applications in the semi-cap equipment market.

Another exceptional feature of the PA52 is a boost voltage input that allows the small signal portion of the amplifier to operate at a higher voltage than the high current output stage. The amplifier is then biased to achieve close linear swings to the supply rails at high currents for extra efficient operation.

The PA52A is the A grade version providing enhance performance in the areas of offset voltage and voltage swing. The PA52 series is a hybrid product design housed in an electrically isolated, hermetically sealed, 12-pin PowerDIP metal package. For continuous operation under load, a heatsink of proper rating is recommended.
