The PA50 is a 40A, 100V power operational amplifier featuring 200kHz 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 PA50 is targeted for applications in the semi-cap equipment market.
Another exceptional feature of the PA50 is its boost voltage inputs that allow 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 PA50A is the A grade version providing enhance performance in the areas of offset voltage and voltage swing. The PA50 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.
