LM747 Dual 741 Operational Amplifier

Contents hide

The LM747 is a general-purpose dual operational amplifier. The IC offers features such as no latch-up when input common-mode range is exceeded, freedom from oscillations, and package flexibility. The IC is available in an 8-pin hermetically sealed dual inline IC packaging (DIP). LM1458 has a wide variety of working conditions and voltages. The output of the IC is directly compatible with almost every CMOS, PMOS, and NMOS device. The IC also offers many additional features such as high noise immunity, short circuit protection, and low power dissipation.

Operational Amplifier

Operational amplifiers are simple electronic circuits that can boost a weak signal to a level of higher amplitude. An operational amplifier is generally used in applications such as home entertainment systems, megaphones, speakers, and microphones, etc. An op-amp usually operates with a number of feedback components that determine the resulting function or “operation” of the amplifier and by virtue of the different feedback, configurations whether resistive, capacitive, or both.
