Product Summary

The PB58R 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 output voltage range and current capability of the booster. The PB58R can also be used without a driver in some applications, requiring only an external current limit resistor to function properly. Applications are (1)High voltage instrumentation; (2)Electrostatic transducers & deflection; (3)Programmable power supplies up to 280v p-p.
