DESCRIPTION
The PB50 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
PB50 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-
ary breakdown limitations imposed by Bipolar Junction Tran-
sistors. Internal feedback and gainset resistors are provided
for a pin-strappable 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. Although the booster can be
configured quite simply, 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 8-pin TO-3
package is electrically isolated and hermetically sealed using
one-shot resistance welding. The use of compressible isola-
tion washers voids the warranty.
