FEATURES

DESCRIPTION

The LMC6442 is ideal for battery powered systems,

•

where very low supply current (less than one

•

Output Swing to Within 30 mV of Supply Rail

microamp per amplifier) and Rail-to-Rail output swing

•

High Voltage Gain 103 dB

is required. It is characterized for 2.2V to 10V

operation, and at 2.2V supply, the LMC6442 is ideal

•

Gain Bandwidth Product 9.5 KHz

for single (Li-Ion) or two cell (NiCad or alkaline)

•

Ensured for: 2.2V, 5V, 10V

battery systems.

•

Low Supply Current 0.95 µA/Amplifier

The LMC6442 is designed for battery powered

•

Input Voltage Range

systems that require long service life through low

2.1 µW/Amplifier Power Consumption

supply current, such as smoke and gas detectors,

and pager or personal communications systems.

•

Operation from single supply is enhanced by the wide

APPLICATIONS

common mode input voltage range which includes the

ground (or negative supply) for ground sensing

•

Portable Instruments

applications. Very low (5 fA, typical) input bias current

•

Smoke/Gas/CO/Fire Detectors

and near constant supply current over supply voltage

•

Pagers/Cell Phones

enhance the LMC6442's performance near the end-

of-life battery voltage.

•

Instrumentation

•

Thermostats

Designed for closed loop gains of greater than plus

two (or minus one), the amplifier has typically 9.5

also allows capacitive loads of up to 300 pF to be

driven, as described in the Application Information

section.

These devices have limited built-in ESD protection. The leads should be shorted together or the device placed in conductive foam

during storage or handling to prevent electrostatic damage to the MOS gates.
