LMC6035/LMC6036

Low Power 2.7V Single Supply CMOS Operational

Amplifiers

General Description

The LMC6035/6 is an economical, low voltage op amp ca-

pable of rail-to-rail output swing into loads of 600

Ω.

LMC6035 is available in a chip sized package (8-Bump

micro SMD) using National’s micro SMD package technol-

ogy. Both allow for single supply operation and are guaran-

teed for 2.7V, 3V, 5V and 15V supply voltage. The 2.7 supply

voltage corresponds to the End-of-Life voltage (0.9V/cell) for

three NiCd or NiMH batteries in series, making the

LMC6035/6 well suited for portable and rechargeable sys-

tems. It also features a well behaved decrease in its speci-

fications at supply voltages below its guaranteed 2.7V op-

eration. This provides a “comfort zone” for adequate

operation at voltages significantly below 2.7V. Its ultra low

input currents (I

IN) makes it well suited for low power active

filter application, because it allows the use of higher resistor

values and lower capacitor values. In addition, the drive

capability of the LMC6035/6 gives these op amps a broad

range of applications for low voltage systems.
