DESCRIPTION
The OPA349 and OPA2349 are ultra-low power op-
erational amplifiers that provide 70kHz bandwidth
with only 1
μ
A quiescent current. These rail-to-rail
input and output amplifiers are specifically designed
for battery powered applications. Unlike some
micropower op amps, these parts are unity-gain stable
and require no external compensation. The OPA349’s
low input bias current allows the use of large source
and feedback resistors. The input common-mode volt-
age range extends 200mV beyond the power supply
rails and the output swings to within 150mV of the
rails, maintaining wide dynamic range.
OPA349 can be operated with power supplies from
1.8V to 5.5V with little change in performance, guar-
anteeing continuing superior performance even in low
battery situations.
OPA349 comes in the miniature SOT23-5, SO-8 sur-
face mount and PDIP-8
(1)
packages. OPA2349 dual is
also available in the SOT23 (8-lead SOT23-8), as well
as the SO-8 surface mount packages. These tiny pack-
ages are ideal for use in high-density applications,
such as PCMCIA cards, battery packs and portable
instruments.
All models are specified for the commercial tempera-
ture range, 0
°
C to +70
°
C.
