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 High Input Impedance (Z ) 1.5TΩ (Typ)

- Very Low Input Current (I ) 10pA (Typ) at ± 15V

- Wide Common-Mode Input Voltage Range (V

Be Swung 0.5V Below Negative Supply Voltage Rail

• 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).
