PB58A POWER BOOSTER AMPLIFIERS

PB58A POWER BOOSTER AMPLIFIERS

The PB58 is a high voltage, high current amplifier designed to provide voltage and current gain for a small signal, general purpose op amp. Including the power booster within the feedback loop of the driver amplifier results in a composite amplifier with the accuracy of the driver and the extended o.
