|LMC272 CMOS Dual Low Cost Rail to Rail Output Operational Amplifier
The is a CMOS dual operational amplifier with rail-to-rail output swing and an input common voltage range that extends below the negative supply. Other performance characteristics include low voltage operation, low bias current, excellent channel-to-channel isolation, good bandwidth performance and a competitive price. These devices are available in MSOP package which is about half the size a SO-8 device. This enables the designer to fit the device in extremely small applications. The is a direct replacement for TLC272C with performance which meets or exceeds the TLC272C's guaranteed limits in the commercial temperature range when operating from a supply to 15V (see Electrical Characteristics table for details). These features make this cost effective device ideal for new designs as well as for upgrading existing designs. Applications include hand-held analytic instruments, transducer amplifiers, sample and hold circuits, etc.Features
