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 perfor-
mance (1MHz GBW and 0.6V/µs SR) and unity-gain stabil-
ity. 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 surface-
mount, 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 pack-
ages. All are specified for operation from –40°C to +85°C.
