SO-8 Single/Dual SSOP-16 Quad (Obsolete) SOT-23-5 Single MSOP Dual OPA237 OPA2237 OPA4237 SBOS057A - OCTOBER 1996 - REVISED FEBRUARY 2007 SINGLE-SUPPLY OPERATIONAL AMPLIFIERS MicroAmplifierE Series FEATURES DESCRIPTION D MICRO-SIZE, MINIATURE PACKAGES: The OPA237 op amp family is one of Texas Instruments' MicroAmplifier series of miniature products. In addition 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 flexibility. They are ideal for single-supply, battery-operated, and space-limited applications, such as PCMCIA cards and other portable instruments. - Single: SOT23-5, SO-8 - Dual: MSOP-8, SO-8 - Quad: SSOP-16 (Obsolete) LOW OFFSET VOLTAGE: 750V max D D WIDE SUPPLY RANGE: D D - Single Supply: +2.7V to +36V - Dual Supply: +1.35V to +18V LOW QUIESCENT CURRENT: 350V max WIDE BANDWIDTH: 1.5MHz 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 independent circuitry for lowest crosstalk and freedom from interaction. APPLICATIONS D D D D D BATTERY-POWERED INSTRUMENTS PORTABLE DEVICES PCMCIA CARDS MEDICAL INSTRUMENTS TEST EQUIPMENT Single, dual, and quad are offered in space-saving surface-mount packages. The single version is available in the ultra-miniature 5-lead SOT23-5 and SO-8 surface-mount. The dual version comes in a miniature MSOP-8 and SO-8 surface-mount. The quad version is obsolete. MSOP-8 has the same lead count as a SO-8 but half the size. The SOT23-5 is even smaller at one-fourth the size of an SO-8. All are specified for -40C to +85C operation. A macromodel is available for design analysis.

These are stress ratings only, and functional operation of the device at these or any other conditions beyond those specified is not implied. 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.

Furthermore, in single-supply applications where the load is connected to ground, the op amp is only sourcing current, and as shown Figure 1, can drive 10,000pF with output currents up to 1.5mA. 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 capacitors. OPERATING VOLTAGE 100k 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 throughout 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. Capacitive Load (pF) OPERATION NOT RECOMMENDED 10k 1k VS = +5V, 15V 100 OUTPUT CURRENT AND STABILITY VS = +2.7V 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.

Pb-Free (RoHS Exempt): This component has a RoHS exemption for either 1) lead-based flip-chip solder bumps used between the die and package, or 2) lead-based die adhesive used between the die and leadframe. The component is otherwise considered Pb-Free (RoHS compatible) as defined above. Green (RoHS & no Sb/Br): TI defines "Green" to mean Pb-Free (RoHS compatible), and free of Bromine (Br) and Antimony (Sb) based flame retardants (Br or Sb do not exceed 0.1% by weight in homogeneous material) (3) MSL, Peak Temp. - The Moisture Sensitivity Level rating according to the JEDEC industry standard classifications, and peak solder temperature. (4) There may be additional marking, which relates to the logo, the lot trace code information, or the environmental category on the device. (5) Multiple Device Markings will be inside parentheses. Only one Device Marking contained in parentheses and separated by a "~" will appear on a device. If a line is indented then it is a continuation of the previous line and the two combined represent the entire Device Marking for that device. (6) Lead/Ball Finish - Orderable Devices may have multiple material finish options. Finish options are separated by a vertical ruled line. Lead/Ball Finish values may wrap to two lines if the finish value exceeds the maximum column width.
