The PAD112 high voltage operational amplifier is
constructed with surface mount components to
provide a cost effective solution for many
industrial applications. With a footprint only 3.8
in
that rivals more expensive hybrid component
amplifiers
selectable external compensation tailors the
amplifier’s
requirements. Four-wire programmable current
limit is built-in but the PAD112 is also compatible
with the precision PAD123 Current Limit
Accessory Module. The PAD112 also features a
substrate temperature reporting output and over-
temp shutdown. The amplifier circuitry is built on
a thermally conductive but electrically insulating
substrate mounted to an integral heat sink and fan
assembly. No BeO is used in the PAD112. The
resulting module is a small, high performance
turn-key solution for many industrial applications.

the
application
User
A critical task in any power amplifier application
is cooling the amplifier. Until now component
amplifier manufacturers often treated this task as
an after-thought, left for the user to figure out. At
Power Amp Design the best heat sink and fan is
chosen at the start and becomes an integral part of
the overall amplifier design. The result is the most
compact
combination at the lowest cost. In addition, this
integrated solution concept offers an achievable
real-world power dissipation rating, not the ideal
rating usually cited when the amplifier case is
somehow kept at 25
