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
Features
• Dual Version of CA3140
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.

NOTE: Intersil Pb-free products employ special Pb-free material sets;
molding compounds/die attach materials and 100% matte tin plate termination
finish, which are RoHS compliant and compatible with both SnPb and Pb-free
soldering operations. Intersil Pb-free products are MSL classified at Pb-free
peak reflow temperatures that meet or exceed the Pb-free requirements of
IPC/JEDEC J STD-020.
