DESCRIPTION
The OPA705 series low-cost op amps are optimized for appli-
cations requiring rail-to-rail input and output swing. Single,
dual, and quad versions are offered in a variety of packages.
While the quiescent current is less than 200 μA per amplifier,
the OPA705 still offers excellent dynamic performance
(1MHz GBW and 0.6V/ μs SR) and unity-gain stability.
The OPA705 series is fully specified and guaranteed over
the supply range of ±2V to ±6V. Input swing extends
300mV beyond the rail and the output swings to within
40mV of the rail.
The single version (OPA705) is available in the MicroSIZE
SOT23-5 and in the standard SO-8 surface-mount packages.
The dual version (OPA2705) is available in the MSOP-8,
SO-8, and DIP-8 packages. The quad OPA4705 is available
in the TSSOP-14 and SO-14 packages. All are specified for
operation from –40 °C to +85 °C.

Signal Input Terminals, Voltage (2) ..................... (V–) –0.3V to (V+) +0.3V
Current(2) .................................................... 10mA
Output Short-Circuit (3) .............................................................. Continuous

Lead Temperature (soldering, 10s) ............................................... +300°C
NOTES: (1) Stresses above these ratings may cause permanent damage.
Exposure to absolute maximum conditions for extended periods may
degrade device reliability. (2) Input terminals are diode-clamped to the power
supply rails. Input signals that can swing more than 0.3V beyond the supply
rails should be current-limited to 10mA or less. (3) Short-circuit to ground,
one amplifier per package.
ABSOLUTE MAXIMUM RATINGS (1)
ELECTROSTATIC
DISCHARGE SENSITIVITY
This integrated circuit can be damaged by ESD. Texas Instru-
ments recommends that all integrated circuits be handled with
appropriate precautions. Failure to observe proper handling
and installation procedures can cause damage.
ESD damage can range from subtle performance degrada-
tion to complete device failure. Precision integrated circuits
may be more susceptible to damage because very small
parametric changes could cause the device not to meet its
published specifications.
