Description
The CA3240A and CA3240 are dual versions of the popular CA3140 series integrated circuit operational amplifiers. They combine the advantages of MOS and bipolar transistors on the same monolithic chip. The gate-protected MOSFET (PMOS) input transistors provide high input impedance and a wide common-mode input voltage range (typically to 0.5V below the negative supply rail). The bipolar output transistors allow a wide output voltage swing and provide a high output current capability. The CA3240A and CA3240 are compatible with the industry standard 1458 operational amplifiers in similar packages.

FAQ
What is Bimos operational amplifier?
w/MOSFET Input, Bipolar Output. Description: The NTE7144 is an integrated circuit operational amplifier in an 8–Lead Mini–DIP type package that combines the advantages of high–voltage PMOS transistors with high–voltage bipolar transistors on a single monolithic chip.
What is operational amplifier?
An operational amplifier is an integrated circuit that can amplify weak electric signals. An operational amplifier has two input pins and one output pin. Its basic role is to amplify and output the voltage difference between the two input pins.
Why is it called operational amplifier?
Originally, op-amps were so named because they were used to model the basic mathematical operations of addition, subtraction, integration, differentiation, etc. in electronic analog computers. In this sense a true operational amplifier is an ideal circuit element.
