DESCRIPTION
The LMC6442 is ideal for battery powered systems,
where very low supply current (less than one
microamp per amplifier) and Rail-to-Rail output swing
is required. It is characterized for 2.2V to 10V
operation, and at 2.2V supply, the LMC6442 is ideal
for single (Li-Ion) or two cell (NiCad or alkaline)
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 communications systems.
Operation from single supply is enhanced by the wide
common mode input voltage range which includes the
ground (or negative supply) for ground sensing
applications. Very low (5 fA, typical) input bias current
and near constant supply current over supply voltage
enhance the LMC6442's performance 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 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.

(1) Absolute Maximum Ratings indicate limits beyond which damage to the device may occur. Operating Ratings indicate conditions for
which the device is intended to be functional, but specific performance is not ensured. For ensured specifications and the test
conditions, see the Electrical Characteristics.
(2) If Military/Aerospace specified devices are required, please contact the TI Sales Office/ Distributors for availability and specifications.
(3) Human body model, 1.5 kΩ in series with 100 pF.
(4) Limiting input pin current is only necessary for input voltages that exceed absolute maximum input voltage ratings.
(5) Applies to both single-supply and split-supply operation. Continuous short circuit operation at elevated ambient temperature can result in
exceeding the maximum allowed junction temperature of 150°C. Output currents in excess of ±30 mA over long term may adversely
affect reliability.
(6) Do not short circuit output to V+, when V+ is greater than 13V or reliability will be adversely affected.
(7) The maximum power dissipation is a function of TJ(MAX), θJA, and TA. The maximum allowable power dissipation at any ambient
temperature is PD= (TJ(MAX) - TA)/ θJA. All numbers apply for packages soldered directly into a PC board.
