Data Sheet  
August 2001  
File Number 1050.5  
Dual, 4.5MHz, BiMOS Operational Amplifier  
with MOSFET Input/Bipolar Output  
Features  
• Dual Version of CA3140  
• Internally Compensated  
• MOSFET Input Stage  
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.

- Very Low Input Current (I ) 10pA (Typ) at ± 15V  
- Wide Common-Mode Input Voltage Range (V

• Directly Replaces Industry Type 741 in Most Applications  
Applications  
The CA3240A and CA3240 are compatible with the industry  
standard 1458 operational amplifiers in similar packages.The  
offset null feature is available only when these types are supplied  
in the 14 lead PDIP package (E1 suffix).
