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 feed-

backloopofthedriverampliﬁerresultsinacompositeampliﬁer

withtheaccuracyofthedriverandtheextendedoutputvoltage

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.

TheoutputstageutilizescomplementaryMOSFETs,provid-

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.

–Vs

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-shotresistancewelding.Theuseofcompressibleisolation

washers voids the warranty.
