DESCRIPTION
The PA13 is a state of the art high voltage, very high output
current operational amplifier designed to drive resistive, in-
ductive and capacitive loads. For optimum linearity, especially
at low levels, the output stage is biased for class A/B operation
using a thermistor compensated base-emitter voltage mul-
tiplier circuit. The safe operating area (SOA) can be observed
for all operating conditions by selection of user program-
mable current limiting resistors. For continuous operation
under load, a heatsink of proper rating is recommended.
This hybrid integrated circuit utilizes thick film (cermet)
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.
THERMAL STABILITY
APEX has eliminated the tendency of class A/B output
stages toward thermal runaway and thus has vastly increased
amplifier reliability. This feature, not found in most other Power
Op Amps, was pioneered by APEX in 1981 using thermistors
which assure a negative temperature coefficient in the quies-
cent current. The reliability benefits of this added circuitry far
outweigh the slight increase in component count.
POWER RATING
Not all vendors use the same method to rate the power
handling capability of a Power Op Amp. APEX rates the
internal dissipation, which is consistent with rating methods
used by transistor manufacturers and gives conservative
results. Rating delivered power is highly application depen-
dent and therefore can be misleading. For example, the 135W
internal dissipation rating of the PA13 could be expressed as
an output rating of 260W for audio (sine wave) or as 440W if
using a single ended DC load. Please note that all vendors rate
maximum power using an infinite heatsink.
