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 feed-
back 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 utilizes complementary MOSFETs, pro-
viding symmetrical output impedance and eliminating second
breakdown limitations imposed by Bipolar Transistors. Internal
feedback and gainset resistors 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 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 inter-
connections at all operating temperatures. The 12-pin Power
SIP package is electrically isolated.
