DESCRIPTION

The OPA703 and OPA704 series op amps are optimized for
applications 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 200µA per
amplifier, the OPA703 still offers excellent dynamic perfor­mance (1MHz GBW and 0.6V/µs SR) and unity-gain stabil­ity. The OPA704 is optimized for gains of 5 or greater and
provides 3MHz GBW and 3V/µs slew rate.

The OPA703 and OPA704 series are 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 versions (OPA703 and OPA704) are available in
the MicroSIZE SOT23-5 and in the standard SO-8 surface­mount, as well as the DIP-8 packages. Dual versions
(OPA2703 and OPA2704) are available in the MSOP-8,
SO-8, and DIP-8 packages. The quad OPA4703 and
OPA4704 are available in the TSSOP-14 and SO-14 pack­ages. All are specified for operation from –40°C to +85°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,

ELECTROSTATIC
DISCHARGE SENSITIVITY

This integrated circuit can be damaged by ESD. Texas Instru­ments 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 degrada­tion 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.
