... Data Sheet 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 ...
