NTE7141 Integrated Circuit Dual BIMOS Operational Amplifier w/MOSFET Input, Bipolar Output Description: The NTE7141 is a dual, operational amplifier in an 8–Lead Mini–DIP type package that combines the advantages of MOS and bipolar transistors on the same monolithic chip. The gate–protected MOSFET (PMOS) input transistors provide high input impredance 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.
