LMC6442  
Dual Micropower Rail-to-Rail Output Single Supply  
Operational Amplifier  
General Description  
Key Specifications  
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.  
Gain Bandwidth Product  
9.5 KHz  
Guaranteed for:  
2.2V, 5V, 10V  
0.95 µA/Amplifier

Low Supply Current  
Input Voltage Range  
Power consumption  
Stable for AV ≥+2 or AV ≤ −1  
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.  
Applications  
n Portable instruments  
n Smoke/gas/CO/fire detectors  
n Pagers/cell phones  
n Instrumentation  
n Thermostats  
n Occupancy sensors  
n Cameras  
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.
