Data Sheet
March 4, 2005
Dual, 4.5MHz, BiMOS Operational Amplifier
with MOSFET Input/Bipolar Output
Features
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.
FN1050.6
• Internally Compensated
The CA3240A and CA3240 are compatible with the industry
standard 1458 operational amplifiers in similar packages.
• MOSFET Input Stage
- Very High Input Impedance (ZIN) 1.5TΩ (Typ)
- Very Low Input Current (II) 10pA (Typ) at ±15V
- Wide Common-Mode Input Voltage Range (VICR): Can
Be Swung 0.5V Below Negative Supply Voltage Rail
• Directly Replaces Industry Type 741 in Most Applications
• Pb-Free Available (RoHS Compliant)
Applications
• Ground Referenced Single Amplifiers in Automobile and
Portable Instrumentation

Pb-free PDIPs can be used for through hole wave solder processing only.
They are not intended for use in Reflow solder processing applications.
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.
