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 600Ω.
LMC6035 is available in a chip sized package (8-Bump mi-
cro SMD) using National’s micro SMD package technology.
Both allow for single supply operation and are guaranteed
for 2.7V, 3V, 5V and 15V supply voltage. The 2.7 supply volt-
age 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 specifi-
cations at supply voltages below its guaranteed 2.7V opera-
tion. This provides a “comfort zone” for adequate operation
at voltages significantly below 2.7V. Its ultra low input cur-
rents (I
IN
) makes it well suited for low power active filter ap-
plication, 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 appli-
cations for low voltage systems.
