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 TLC272Câs 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.
