LM741 Chinese information

Photocoupler

CA1458, CA1558 (Double Op Amp); CA741C, CA741, LM741 (Single Op Amp) are high gain op amps for military, industrial and commercial applications. These monolithic silicon integrated circuit devices provide output short circuit protection and latch free operation . These types also have a wide range of common modes, differential mode signal range and low offset voltage zeroing capability with the use of appropriate potentials. The 10kΩ potentiometer is used to offset the zeroing type CA741C, CA741 (see Figure 4) type CA1458, CA1558 without specific terminal offset zeroing. Each type of op amp includes a differential input amplifier that effectively drives the gain and emitter follows the complementary output.
The technical data type is the same as the corresponding Taiwan CA brand.
