DESCRIPTION
The LMC6492/LMC6494 amplifiers were specifically
developed for single supply applications that operate
from 40°C to +125°C. This feature is well-suited for
automotive systems because of the wide temperature
range. A unique design topology enables the
LMC6492/LMC6494 common-mode voltage range to
accommodate input signals beyond the rails. This
eliminates non-linear output errors due to input
signals exceeding a traditionally limited common-
mode voltage range. The LMC6492/LMC6494 signal
range has a high CMRR of 82 dB for excellent
accuracy in non-inverting circuit configurations.
The LMC6492/LMC6494 rail-to-rail input is
complemented by rail-to-rail output swing. This
assures maximum dynamic signal range which is
particularly important in 5V systems.
Ultra-low input current of 150 fA and 120 dB open
loop gain provide high accuracy and direct interfacing
with high impedance sources.

(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.

(3) Human body model, 1.5 kΩ in series with 100 pF.
(4) Applies to both single-supply and split-supply operation. Continuous short operation at elevated ambient temperature can result in
exceeding the maximum allowed junction temperature at 150°C. Output currents in excess of ±30 mA over long term may adversely
affect reliability.
(5) 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.
