Part Details:

LM12CL May 1999 80W LM12CL80W Operational Amplifier Operational General Description This monolithic op amp is compensated for unity-gain feed-back, with a small-signal bandwidth of 700 kHz. Slew rate is The LM12 is a power op amp capable of driving ±25V at 9V/µs, even as a follower. Distortion and capacitive-load ±10A while operating from ±30V supplies. The monolithic IC stability rival that of the best designs using complementary can deliver 80W of sine wave power into a 4 load with output transistors. Further, the IC withstands large differen- 0.01% distortion. Power bandwidth is 60 kHz. Further, a tial input voltages and is well behaved should the common- peak dissipation capability of 800W allows it to handle reac- mode range be exceeded. tive loads such as transducers, actuators or small motors The LM12 establishes that monolithic ICs can deliver con- Amplifier without derating. Important features include: siderable output power without resorting to complex switch- · input protection ing schemes. Devices can be paralleled or bridged for even · controlled turn on greater output capability. Applications include operational · thermal limiting power supplies, high-voltage regulators, high-quality audioamplifiers, tape-head positioners, x-y plotters or other servo- · overvoltage shutdown control systems. · output-current limiting The LM12 is supplied in a four-lead, TO-3 package with V- · dynamic safe-area protection on the case. A gold-eutectic die-attach to a molybdenum The IC delivers ±10A output current at any output voltage interface is used to avoid thermal fatigue problems. The yet is completely protected against overloads, including LM12 is specified for either military or commercial tempera- shorts to the supplies. The dynamic safe-area protection is ture range. provided by instantaneous peak-temperature limiting withinthe power transistor array. The turn-on characteristics are controlled by keeping theoutput open-circuited until the total supply voltage reaches14V. The output is also opened as the case temperatureexceeds 150°C or as the supply voltage approaches theBV of the output transistors. The IC withstands overvolt- CEO ages to 80V.
