1 / 15 page 1 CA3240, CA3240A Dual, 4.5MHz, BiMOS Operational Amplifier with MOSFET Input/Bipolar Output 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. TheCA3240A andCA3240are compatible with theindustry standard 1458 operational amplifiers in similar packages.The offset null feature is available only when these types are supplied in the14leadPDIPpackage (E1suffix). Functional Diagram Features • Dual Version of CA3140 • Internally Compensated • 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 Applications • Ground Referenced Single Amplifiers in Automobile and Portable Instrumentation • Sample and Hold Amplifiers • Long Duration Timers/Multivibrators (Microseconds- Minutes-Hours) • Photocurrent Instrumentation Pinouts CA3240, CA3240A (PDIP) TOP VIEW CA3240A (PDIP) TOP VIEW Ordering Information PART NUMBER TEMP.
