LMC6442
Dual Micropower Rail-to-Rail Output Single Supply
Operational Amplifier
General Description
The LMC6442 is ideal for battery powered systems, where
very low supply current (less than one microamp per ampli-
fier) and Rail-to-Rail output swing is required. It is character-
ized for 2.2V to 10V operation, and at 2.2V supply, the
LMC6442 is ideal for single (Li-Ion) or two cell (NiCad or al-
kaline) battery systems.
The LMC6442 is designed for battery powered systems that
require long service life through low supply current, such as
smoke and gas detectors, and pager or personal communi-
cations systems.
Operation from single supply is enhanced by the wide com-
mon mode input voltage range which includes the ground (or
negative supply) for ground sensing applications. Very low
(5fA, typical) input bias current and near constant supply cur-
rent over supply voltage enhance the LMC6442’s perfor-
mance near the end-of-life battery voltage.
Designed for closed loop gains of greater than plus two (or
minus one), the amplifier has typically 9.5 KHz GBWP (Gain
Bandwidth Product). Unity gain can be used with a simple
compensation circuit, which also allows capacitive loads of
up to 300 pF to be driven, as described in the Application
Notes section.
For compact assembly the LMC6442 is available in the
MSOP 8 pin package, about one half the size required by the
SOIC 8 pin package. 8 pin DIP and 8 pin SOIC are also
available.
