LM12CL

80W Operational Amplifier

ceeds 150˚C or as the supply voltage approaches the

BV_CEOof the output transistors. The IC withstands overvolt-

ages to 80V.

General Description

The LM12 is a power op amp capable of driving 25V at

10A while operating from 30V supplies. The monolithic IC

This monolithic op amp is compensated for unity-gain feed-

back, with a small-signal bandwidth of 700 kHz. Slew rate is

9V/µs, even as a follower. Distortion and capacitive-load sta-

bility rival that of the best designs using complementary out-

put transistors. Further, the IC withstands large differential

input voltages and is well behaved should the

common-mode range be exceeded.

can deliver 80W of sine wave power into a 4Ω load with

0.01% distortion. Power bandwidth is 60 kHz. Further, a

peak dissipation capability of 800W allows it to handle reac-

tive loads such as transducers, actuators or small motors

without derating. Important features include:

•

input protection

controlled turn on

The LM12 establishes that monolithic ICs can deliver consid-

erable output power without resorting to complex switching

schemes. Devices can be paralleled or bridged for even

greater output capability. Applications include operational

power supplies, high-voltage regulators, high-quality audio

amplifiers, tape-head positioners, x-y plotters or other

servo-control systems.

thermal limiting

overvoltage shutdown

output-current limiting

dynamic safe-area protection

The IC delivers 10A output current at any output voltage

yet is completely protected against overloads, including

shorts to the supplies. The dynamic safe-area protection is

provided by instantaneous peak-temperature limiting within

the power transistor array.

The LM12 is supplied in a four-lead, TO-3 package with V−

on the case. A gold-eutectic die-attach to a molybdenum in-

terface is used to avoid thermal fatigue problems. The LM12

is specified for either military or commercial temperature

range.

The turn-on characteristics are controlled by keeping the

output open-circuited until the total supply voltage reaches

14V. The output is also opened as the case temperature ex-
