DESCRIPTION
The OPA237 op amp family is one of Burr-Brown’s
MicroAmplifier series of miniature products. In addi-
tion to small size, these devices feature low offset
voltage, low quiescent current, low bias current, and a
wide supply range. Single, dual, and quad versions
have identical specifications for maximum design flex-
ibility. They are ideal for single supply, battery oper-
ated, and space-limited applications, such as PCMCIA
cards and other portable instruments.
OPA237 series op amps can operate from either single
or dual supplies. When operated from a single supply,
the input common-mode range extends below ground
and the output can swing to within 10mV of ground.
Dual and quad designs feature completely indepen-
dent circuitry for lowest crosstalk and freedom from
interaction.
Single, dual, and quad are offered in space-saving
surface-mount packages. The single version is available
in the ultra-miniature 5-lead SOT-23-5 and SO-8 sur-
face-mount. The dual version comes in a miniature
MSOP-8 and SO-8 surface-mount. The quad is avail-
able in an SSOP-16. The SSOP-16 has the same body
size as an SO-8 with 16 leads, while the MSOP-8 has the
same lead count as a SO-8 but half the size. The
SOT-23-5 is even smaller at one-fourth the size of an
SO-8. All are specified for –40°C to +85 °C operation. A
macromodel is available for design analysis.

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.

OPA237, 2237, 4237
APPLICATIONS INFORMATION
OPA237 series op amps are unity-gain stable and suitable
for a wide range of general-purpose applications. Power
supply pins should be bypassed with 10nF ceramic capaci-
tors.
OPERATING VOLTAGE
OPA237 series op amps operate from single (+2.7V to
+36V) or dual (±1.35V to ±18V) supplies with excellent
performance. Most behavior remains unchanged through-
out the full operating voltage range. Parameters which
vary significantly with operating voltage are shown in
typical performance curves. Specifications are production
tested with +2.7V, +5V, and ±15V supplies.
OUTPUT CURRENT AND STABILITY
OPA237 series op amps can drive large capacitive loads.
However, under certain limited output conditions any op
amp may become unstable. Figure 1 shows the region
where the OPA237 has a potential for instability. These
load conditions are rarely encountered, especially for single
supply applications. For example, take the case when a
+5V supply with a 10kΩ load to VS/2 is used. OPA237
series op amps remain stable with capacitive loads up to
4,000pF, if sinking current and up to 10,000pF, if sourcing
current. Furthermore, in single supply applications where
the load is connected to ground, the op amp is only
sourcing current, and as shown in Figure 1, can drive
10,000pF with output currents up to 1.5mA.
