DESCRIPTION
The LMC6484 provides a common-mode range that
extends to both supply rails. This rail-to-rail
performance combined with excellent accuracy, due
to a high CMRR, makes it unique among rail-to-rail
input amplifiers.
It is ideal for systems, such as data acquisition, that
require a large input signal range. The LMC6484 is
also an excellent upgrade for circuits using limited
common-mode range amplifiers such as the TLC274
and TLC279.
Maximum dynamic signal range is assured in low
voltage and single supply systems by the LMC6484's
rail-to-rail output swing. The LMC6484's rail-to-rail
output swing is ensured for loads down to 600Ω.
Ensured low voltage characteristics and low power
dissipation make the LMC6484 especially well-suited
for battery-operated systems.
See the LMC6482 data sheet for a Dual CMOS
operational amplifier with these same features.

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 functional, but do not ensure specific performance limits. For ensured specifications and test conditions, see the
Electrical Characteristics. The ensured specifications apply only for the test conditions listed. Some performance characteristics may
degrade when the device is not operated under the listed test conditions.
(2) Limiting input pin current is only necessary for input voltages that exceed absolute maximum input voltage ratings.
(3) 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.
(4) Do not short circuit output to V+, when V+ is greater than 13V or reliability will be adversely affected.
(5) The maximum power dissipation must be derated at elevated temperatures and is dictated by TJmax (maximum junction temperature),
θJA (package junction to ambient thermal resistance), and TA (ambient temperature). The maximum allowable power dissipation at any
temperature is PDmax = (TJmax - TA)/θJA or the number given in the Absolute Maximum Ratings, whichever is lower.
(6) All numbers apply for packages soldered directly into a PC board.
