High power operational amplifier 01

L M12 is a high-power operational amplifier integrated circuit launched by National Semiconductor (NS) in the United States
. Its power can reach 150w at 4fl load, the distortion is only 0.ol%, and the power
bandwidth is 60kHz. When driving a reactive load, the output The power can reach 8DOW.
    I.M12 has the following features: input protection ~ controlled start-up, thermal limit, over-voltage cut-off
and dynamic safety range protection port
    1. M12 is a four-pin T()-3 package, as shown in Figure 5-137 display, connect the shell to - vu:,
and connect to [? ] face is gold and molybdenum to prevent thermal fatigue. The internal equivalent circuit is
shown in Figure 5-138.
    1, M】2 can output considerable
power without any complicated switch design. They can also be connected in parallel or bridged to obtain greater output power . The integrated circuit
can be used in power supplies, high-voltage voltage regulators, high-performance audio amplifiers, X-instruments, plotters
, and other servo control systems. As shown in Figure 5-140,
I is recommended by NS Company . The principle of audio power amplifier installed in M12 is solid. For readers' reference.
