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 D MICRO-SIZE, MINIATURE PACKAGES: − Single: SOT23-5, SO-8 − Dual: MSOP-8, SO-8 − Quad: SSOP-16 (Obsolete) LOW OFFSET VOLTAGE: 750µV max − Single Supply: +2.7V to +36V − Dual Supply: +1.35V to +18V LOW QUIESCENT CURRENT: 350µV max WIDE BANDWIDTH: 1.5MHz DESCRIPTION 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. 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. 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 The quad version is obsolete.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 −40°C to +85°C operation. A macromodel is available for design analysis.

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. (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, and functional operation of the device at these or any other conditions beyond those specified is not implied. (2) Short circuit to ground, one amplifier per package.

Power supply pins should be bypassed with 10nF ceramic capacitors. 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 Figure 1, can drive 10,000pF with output currents up to 1.5mA. 100k OPERATION NOT RECOMMENDED Capacitive Load (pF) 10k 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 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. 1k VS = +5V, ±15V VS = +2.7V 10 −2 −1.5 −1 −0.5 0 0.5 1 1.5 2 Output Current (mA) 100 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. RH 10Ω Figure 1.

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.
