The LMC6035/6 is an economical, low voltage op amp capable of rail-to-rail output swing into loads of 600. LMC6035 is available in a chip sized package (8-Bump micro 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 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 systems. It also features a well behaved decrease in its specifications at supply voltages below its guaranteed 2.7V operation. This provides a "comfort zone" for adequate operation at voltages significantly below 2.7V. Its ultra low input currents (IIN) 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.
