1 / 14 page LM12CL 80W Operational Amplifier General Description The LM12 is a power op amp capable of driving ±25V at ±10A while operating from ±30V supplies. The monolithic IC can deliver 80W of sine wave power into a 4 Ω 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 • 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 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- ceeds 150˚C or as the supply voltage approaches the BV CEO of the output transistors. The IC withstands overvolt- ages to 80V. 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. 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. 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. Connection Diagram Typical Application* DS008704-1 4-pin glass epoxy TO-3 socket is available from AUGAT INC.
