3 Description
The LMC6035 and LMC6036 (LMC603x) are
economical, low-voltage op amps capable of rail-torail
output swing into loads of 600Ω. The LMC6035
is available in a chip-sized package (8-bump DSBGA)
using micro SMD package technology. Both devices
allow for single-supply operation and are specified
for 2.7V, 3V, 5V, and 15V supply voltage. The
2.7V supply voltage corresponds to the end-of-life
voltage (0.9V/cell) for three NiCd or NiMH batteries
in series, making the LMC603x an excellent choice for
portable and rechargeable systems. These devices
also feature a well behaved decrease in specifications
at supply voltages less than the specified 2.7V
operation. This behavior provides a comfort zone
for adequate operation at voltages significantly less
than 2.7V. The ultra-low input current makes these
devices an excellent choice for low-power, activefilter
applications because a low input bias current
allows the use of higher resistor values and lower
capacitor values. In addition, the drive capability of
the LMC603x makes these op amps an excellent
choice in a broad range of applications for low-voltage
systems.
