PB63DP - Dual Power Booster Amplifier, 150V, 2A, 1000 V/µs
The PB63 is a dual high voltage, high current booster 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 current capability of the booster.
The output stage utilizes complementary MOSFETs, providing symmetrical output impedance and eliminating second breakdown limitations imposed by Bipolar Junction Transistors. Although the booster can be configured quite simply, enormous flexibility is provided through the choice of driver amplifier, current limit and supply voltage.
This hybrid circuit 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 PB63 is packaged in Apex Microtechnology’s 12-pin power SIP. The case is electrically isolated.
