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
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.
