DESCRIPTION
The LMC6084 is a precision quad low offset voltage
operational amplifier, capable of single supply
operation. Performance characteristics include ultra
low input bias current, high voltage gain, rail-to-rail
output swing, and an input common mode voltage
range that includes ground. These features, plus its
low offset voltage, make the LMC6084 ideally suited
for precision circuit applications.
Other applications using the LMC6084 include
precision full-wave rectifiers, integrators, references,
and sample-and-hold circuits.
This device is built with National's advanced Double-
Poly Silicon-Gate CMOS process.
For designs with more critical power demands, see
the LMC6064 precision quad micropower operational
amplifier.
For a single or dual operational amplifier with similar
features, see the LMC6081 or LMC6082 respectively.

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 guarantee specific performance limits. For guaranteed specifications and test
conditions, see the Electrical Characteristics. The guaranteed specifications apply only for the test conditions listed.
(2) If Military/Aerospace specified devices are required, please contact the TI Sales Office/ Distributors for availability and specifications.
(3) Do not connect output to V+, when V+ is greater than 13V or reliability will be adversely affected.
(4) 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.
(5) Human body model, 1.5 kΩ in series with 100 pF.
(6) 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.
