CA3240 Datasheet – BiMOS Operational Amplifier – Harris

Part Number: CA3240


BiMOS Operational Amplifier with MOSFET Input/Bipolar Output

Package: 8 Pin DIP Type

Manufacturer: Harris, Intersil




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.
