仕様・特性

CA3240, CA3240A ® 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 Ordering Information PART NUMBER • Dual Version of CA3140 TEMP.

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.
