SO−8 OPA237 Single/Dual SSOP−16 OPA2237 Quad (Obsolete) SOT−23−5 OPA4237 Single MSOPDual SBOS057A − OCTOBER 1996 − REVISED FEBRUARY 2007 SINGLE-SUPPLY OPERATIONAL AMPLIFIERS (cid:2) MicroAmplifier Series FEATURES DESCRIPTION (cid:1) MICRO-SIZE, MINIATURE PACKAGES: The OPA237 op amp family is one of Texas Instruments’ − Single: SOT23-5, SO-8 MicroAmplifier series of miniature products. In addition − Dual: MSOP-8, SO-8 to small size, these devices feature low offset voltage, low − Quad: SSOP-16 (Obsolete) quiescent current, low bias current, and a wide supply (cid:1) LOW OFFSET VOLTAGE: 750µV max range. Single, dual, and quad versions have identical (cid:1) specifications for maximum design flexibility. They are WIDE SUPPLY RANGE: ideal for single-supply, battery-operated, and − Single Supply: +2.7V to +36V space-limited applications, such as PCMCIA cards and − Dual Supply: (cid:1)1.35V to (cid:1)18V other portable instruments. (cid:1) LOW QUIESCENT CURRENT: 350µV max OPA237 series op amps can operate from either single or (cid:1) WIDE BANDWIDTH: 1.5MHz dual supplies. When operated from a single supply, the input common-mode range extends below ground and the APPLICATIONS output can swing to within 10mV of ground. Dual and quad designs feature completely independent circuitry for (cid:1) BATTERY-POWERED INSTRUMENTS lowest crosstalk and freedom from interaction. (cid:1) PORTABLE DEVICES Single, dual, and quad are offered in space-saving (cid:1) surface-mount packages. The single version is available PCMCIA CARDS (cid:1) in the ultra-miniature 5-lead SOT23-5 and SO-8 MEDICAL INSTRUMENTS surface-mount. The dual version comes in a miniature (cid:1) TEST EQUIPMENT MSOP-8 and SO-8 surface-mount. The quad version is obsolete. MSOP-8 has the same lead count as a SO-8 but OPA237 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 Out 1 5 V+ operation. A macromodel is available for design analysis.

LIFEBUY: TI has announced that the device will be discontinued, and a lifetime-buy period is in effect. NRND: Not recommended for new designs. Device is in production to support existing customers, but TI does not recommend using this part in a new design. PREVIEW: Device has been announced but is not in production. Samples may or may not be available. OBSOLETE: TI has discontinued the production of the device. (2) RoHS: TI defines "RoHS" to mean semiconductor products that are compliant with the current EU RoHS requirements for all 10 RoHS substances, including the requirement that RoHS substance do not exceed 0.1% by weight in homogeneous materials. Where designed to be soldered at high temperatures, "RoHS" products are suitable for use in specified lead-free processes. TI may reference these types of products as "Pb-Free". RoHS Exempt: TI defines "RoHS Exempt" to mean products that contain lead but are compliant with EU RoHS pursuant to a specific EU RoHS exemption. Addendum-Page 1

PACKAGE OPTION ADDENDUM www.ti.com 24-Aug-2018 Green: TI defines "Green" to mean the content of Chlorine (Cl) and Bromine (Br) based flame retardants meet JS709B low halogen requirements of <=1000ppm threshold. Antimony trioxide based flame retardants must also meet the <=1000ppm threshold requirement. (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.
