DESCRIPTION
The LMC660 CMOS Quad operational amplifier is
ideal for operation from a single supply. It operates
from +5V to +15.5V and features rail-to-rail output
swing in addition to an input common-mode range
that includes ground. Performance limitations that
have plagued CMOS amplifiers in the past are not a
problem with this design. Input VOS, drift, and
broadband noise as well as voltage gain into realistic
loads (2 kΩ and 600Ω) are all equal to or better than
widely accepted bipolar equivalents.
This chip is built with TI's advanced Double-Poly
Silicon-Gate CMOS process.
See the LMC662 datasheet 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 intended to be 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.
(2) Do not connect output to V+ when V+ is greater than 13V or reliability may be adversely affected.
(3) Applies to both single supply and split supply operation. Continuous short circuit operation at elevated ambient temperature and/or
multiple Op Amp shorts 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) 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.
(5) Human Body Model is 1.5 kΩ in series with 100 pF.
