APEX PB64
The PB64 is a dual high voltage, high current booster amplifier designed to provide voltage and current gain for a small signal, general purpose op amp. The output stage utilizes complementary MOSFETs, providing symmetrical output impedance and elimi‐ nating second breakdown limitations imposed by Bipolar Junction Transistors. This hybrid circuit utilizes a Beryllia (BeO) substrate, thick film resistors, ceramic capacitors and semicon‐ ductor chips to maximize reliability, minimize size and give top performance.FEATURES

DESCRIPTION
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 cur‐ rent capability of the booster. Although the booster can be configured quite simply, enormous flexibility is provided through the choice of driver amplifier, current limit and supply voltage. Ultrasonically bonded alumi‐ num wires provide reliable interconnections at all operating temperatures. The PB64 is packaged in Apex Microtechnology’s 12‐pin power SIP.
