LMC272
CMOS Dual Low Cost Rail to Rail Output Operational
Amplifier
General Description
The LMC272 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 cur-
rent, 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 of a SO-8 device. This enables the de-
signer to fit the device in extremely small applications.
The LMC272C is a direct replacement for TLC272C with per-
formance which meets or exceeds the TLC272C’s guaran-
teed limits in the commercial temperature range when oper-
ating from a supply of 2.7V 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. Applica-
tions include hand-held analytic instruments, transducer am-
plifiers, sample and hold circuits, etc.
