DESCRIPTION
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 PB50 can also
be used without a driver in some applications, requiring only
an external current limit resistor to function properly.
ing symmetrical output impedance and eliminating secondary
breakdown limitations imposed by Bipolar Junction Transis-
tors. 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.
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 isolation
washers voids the warranty.
