DESCRIPTION
The LMC6464 is a micropower version of the popular
LMC6484, combining Rail-to-Rail Input and Output
Range with very low power consumption.
The LMC6464 provides an input common-mode
voltage range that exceeds both rails. The rail-to-rail
output swing of the amplifier, ensured for loads down
to 25 KΩ, assures maximum dynamic signal range.
This rail-to-rail performance of the amplifier,
combined with its high voltage gain makes it unique
among rail-to-rail amplifiers. The LMC6464 is an
excellent upgrade for circuits using limited common-
mode range amplifiers.
The LMC6464, with ensured specifications at 3V and
5V, is especially well-suited for low voltage
applications. A quiescent power consumption of 60
μW per amplifier (at VS = 3V) can extend the useful
life of battery operated systems. The amplifier's 150
fA input current, low offset voltage of 0.25 mV, and
85 dB CMRR maintain accuracy in battery-powered
systems.

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.
(7) Human body model, 1.5 kΩ in series with 100 pF.
