LMC272

CMOS Dual Low Cost Rail to Rail Output Operational

Amplifier

General Description

Features

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.

(Typical unless otherwise noted) V_S5V, T_A25˚C

n Output Swing to within 60 mV of supply rail (10 kΩ load)

n High voltage gain: 90 dB

n Unity gain-bandwidth: 2.0 MHz

n Wide supply voltage: 2.7V to 15V

n Characterized for: 2.7V, 5V, 10V

n Low supply current: 0.975 mA/amplifier

n Input voltage range: −0.3V to 4.2V

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-

Applications

n Portable instruments

n Upgrade for TLC272C and TS272C

n Photodetector preamplifiers

n D/A converters

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.
