The LM1558 are general purpose dual operational amplifiers. The two amplifiers inside this single IC share a common bias network, and power supply leads. Otherwise, their operation is completely independent.
The TDA2822 is a dual low power audio amplifier in an 8-Pin plastic dual in-line package. This IC comes with features like low crossover distortion, low quiescent current, and supply voltage range of this IC is 3V to 15V.
The OP07 is an Ultralow Offset Voltage ((75μV maximum) Operational Amplifier with low input bias current (±4nA) and high open-loop gain (200 V/mV). The OP07 is available in epoxy 8-lead PDIP and 8-lead narrow SOIC packages.
The CA3140 is a 4.5MHz, BiMOS Operational Amplifier with MOSFET Input/Bipolar Output that combines the advantages of high voltage PMOS transistors with high voltage bipolar transistors on a single monolith
