80W Operational Amplifier
General DescriptionThe LM12isa powerop amp capableof driving ±25Vat±10A while operating from ±30V supplies. The monolithicIC
can deliver 80Wof sine wave power intoa 4Ω load with
0.01% distortion. Power bandwidthis60 kHz. Further,a
peak dissipation capabilityof 800W allowsitto handle reac-
tive loads suchas transducers, actuatorsor small motors
without derating. Important features include: input protection controlled turnon thermal limiting overvoltage shutdown output-current limiting dynamic safe-area protection
TheIC delivers ±10A output currentat any output voltage
yetis completely protected against overloads, including
shortstothe supplies. The dynamic safe-area protectionis
providedby instantaneous peak-temperature limiting within
the power transistor array.
The turn-on characteristics are controlledby keeping the
output open-circuited until the total supply voltage reaches
14V. The outputis also openedas the case temperature
exceeds 150˚Coras the supply voltage approaches the
BVCEOofthe output transistors. TheIC withstands overvolt-
agesto 80V.
This monolithicop ampis compensatedfor unity-gain feed-
back, witha small-signal bandwidthof 700 kHz. Slew rateis
9V/µs, evenasa follower. Distortion and capacitive-load
stability rival thatofthe best designs using complementary
output transistors. Further, theIC withstands large differen-
tial input voltages andis well behaved shouldthe common-
mode rangebe exceeded.
The LM12 establishes that monolithic ICs can deliver con-
siderable output power without resortingto complex switch-
ing schemes. Devices canbe paralleledor bridgedfor even
greater output capability. Applications include operational
power supplies, high-voltage regulators, high-quality audio
amplifiers, tape-head positioners,x-y plottersor other servo-
control systems.
The LM12is suppliedina four-lead, TO-3 package withV− the case.A gold-eutectic die-attachtoa molybdenum
interfaceis usedto avoid thermal fatigue problems. The
LM12is specifiedfor either militaryor commercial tempera-
ture range.
