LM1458 Dual Operational Amplifier IC

The LM1458 is a dual operational amplifier IC. A common bias network and power supply lines are shared by the two amplifiers. Aside from that, their operation is fully self-contained. The IC is packaged in an 8-pin dual in line hermetically sealed IC package (DIP). The LM1458 can operate in a broad range of temperatures and voltages. The IC’s output is directly compatible with nearly all CMOS, PMOS, and NMOS devices. Many other benefits of the IC include strong noise immunity, short circuit protection, and low power dissipation.

An operational amplifier is a voltage amplifier that is designed to work with external feedback components such as resistors and capacitors connected to its I/O terminals. By virtue of the various feedback topologies, whether resistive, capacitive, or both, these feedback components define the resultant function or “operation” of the amplifier.

LM747 Dual Operational Amplifier IC offers a unity-gain bandwidth of 1MHz. The frequency range up to which a unity-gain amplifier may run without significantly distorting the signal is known as the unity-gain bandwidth. The slew rate refers to how quickly an operational amplifier may vary its output in response to changes in the input. A similar bias network and power supply lines are shared by the LM747 general purpose twin operational amplifiers. Aside from that, their operation is fully self-contained. Instead of 55°C to +125°C, the LM747 operates in the temperature range of 0°C to +70°C.
