Description

The PB51 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 PB51 can also be used without a driver in some applications, requiring only an external current limit resistor to function properly.

The output stage of PB51A utilizes complementary MOSFETs, providing symmetrical output impedance and eliminating second breakdown limitations imposed by Bipolar Transistors. Internal feedback and gainset resistors PB51A are provided for a pin-strapable gain of 3. Additional gain can be achieved with a single external resistor. Compensation is not required for most driver/gain configurations, but can be accomplished with a single external capacitor. Enormous flexibility is provided through the choice of driver amplifier, current limit, supply voltage, voltage gain,and compensation.

This hybrid circuit of PB51A utilizes a beryllia (BeO) substrate, thick film resistors, ceramic capacitors and semiconductor chips to
maximize reliability, minimize size and give top performance.Ultrasonically bonded aluminum wires provide reliable interconnections at all operating temperatures. The 12-pin Power SIP package is electrically isolated.
