DESCRIPTION
OPA336 series micropower CMOS operational ampli-
fiers are designed for battery-powered applications.
They operate on a single supply with operation as low
as 2.1V. The output is rail-to-rail and swings to within
3mV of the supplies with a 100k
load. The
common-mode range extends to the negative supply--
ideal for single-supply applications. Single, dual, and
quad versions have identical specifications for maxi-
mum design flexibility.
In addition to small size and low quiescent current
(20
A/amplifier), they feature low offset voltage
(125
V max), low input bias current (1pA), and high
open-loop gain (115dB). Dual and quad designs fea-
ture completely independent circuitry for lowest
crosstalk and freedom from interaction.
OPA336 packages are the tiny SOT23-5 surface mount,
SO-8 surface-mount, and DIP-8. OPA2336 comes in
the miniature MSOP-8 surface-mount, SO-8 surface-
mount, and DIP-8 packages. OPA4336 packages are
the space-saving SSOP-16 surface-mount and the DIP-
14. All are specified from 40
C to +85
C and operate
from 55
C to +125
C. A macromodel is available for
design analysis.

NOTES: (1) Models with a slash (/) are available only in Tape and Reel in the quantities indicated (e.g., /2K5 indicates 2500 devices per reel). Ordering 2500 pieces
of "OPA336NA/3K" will get a single 3000 piece Tape and Reel. (2) Grade will be marked on the Reel. (3) SO-8 models also available in Tape and Reel.
PACKAGE/ORDERING INFORMATION
ELECTROSTATIC
DISCHARGE SENSITIVITY
This integrated circuit can be damaged by ESD. Burr-Brown
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.

NOTES: (1) Stresses above these ratings may cause permanent damage.
Exposure to absolute maximum conditions for extended periods may
degrade device reliability. These are stress ratings only. Functional opera-
tion of the device at these conditions, or beyond the specified operating
conditions, is not implied. (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.
