Texas Instruments D-SOIC-ADAPTER-EVM

Overview

D-SOIC-ADAPTER-EVM from Texas Instruments is a depopulated evaluation module that enables rapid prototyping of operational amplifiers in 10 distinct IC packages-including SOT-23 (DCN/DDF, DBV, UDBV), WSON (DSG, DRG, DSE), X2QFN (RUG), SC70 (DCK), X2SON (DPW), and SOT-5X3 (DRL)-onto standard single- or dual-channel SOIC-8 footprints. It supports both shutdown and non-shutdown op amp variants without PCB redesign.

For engineers reviewing the D-SOIC-ADAPTER-EVM datasheet, D-SOIC-ADAPTER-EVM layout, D-SOIC-ADAPTER-EVM BOM, or D-SOIC-ADAPTER-EVM adapter options, this EVM delivers verified mechanical and electrical interface translation for op amp package evaluation across TI's precision analog portfolio-enabling validation of signal integrity, thermal behavior, and board-level compatibility prior to final layout.

Technical Context

The D-SOIC-ADAPTER-EVM implements passive pin-mapped translation between SOIC-8 land patterns and miniature surface-mount packages, with dedicated adapter sections labeled A–J corresponding to specific TI package designators (e.g., DSG, DRG, RUG, DCK). Each section includes optimized trace routing, thermal relief pads, and-where required-auxiliary solder pads for external pull-up/pull-down resistors on shutdown (SD) pins.

It supports two operational configurations: single-channel (5–6 pin devices like SOT-23 DBV/UDBV, SC70 DCK, X2SON DPW) and dual-channel (8–10 pin devices like SOIC-8 compatible SOT-23 DCN/DDF or WSON DSG/DRG), with mechanical score lines enabling clean separation of individual adapter sections from the main panel.

FAQ

What is the primary function of the D-SOIC-ADAPTER-EVM?

The D-SOIC-ADAPTER-EVM is a mechanical and electrical interface adapter that allows engineers to mount and evaluate operational amplifiers in ten different miniature packages-including SOT-23, WSON, X2QFN, SC70, X2SON, and SOT-5X3-onto existing single- or dual-channel SOIC-8 PCB footprints. It eliminates the need for custom PCB spins during op amp qualification, and D-SOIC-ADAPTER-EVM supports both shutdown and non-shutdown device variants via configurable SD pin routing.

Does the D-SOIC-ADAPTER-EVM include populated components?

No, the D-SOIC-ADAPTER-EVM ships depopulated-only the bare PCB with silkscreen labels, solder pads, and score lines. Users must separately source and solder the target op amp device onto the appropriate adapter section (e.g., section C for WSON-DSG, section F for SOT-23-DBV). TI does not supply ICs with the D-SOIC-ADAPTER-EVM, and all devices must be ordered independently using TI's package-specific part numbers.

Which op amp packages are supported by the D-SOIC-ADAPTER-EVM?

The D-SOIC-ADAPTER-EVM supports ten TI package types across single- and dual-channel configurations: SOT-23 (DCN/DDF, DBV, UDBV), WSON (DSG, DRG, DSE), X2QFN (RUG), SC70 (DCK), X2SON (DPW), and SOT-5X3 (DRL). Each is mapped to a labeled section (A–J) on the PCB per Table 3-1 in the SBOU289 user's guide, and D-SOIC-ADAPTER-EVM accommodates both 5/6-pin and 8/10-pin variants without modification.

How do I select the correct adapter section on the D-SOIC-ADAPTER-EVM for my op amp?

Select the adapter section based on your op amp's TI package designator (e.g., DSG, DRG, RUG, DCK) and pin count-referencing Table 3-1 in the D-SOIC-ADAPTER-EVM user's guide. Sections A–J are labeled on the bottom silkscreen; for example, use section D for WSON-DRG devices and section H for X2SON-DPW. The D-SOIC-ADAPTER-EVM user guide includes schematic diagrams (Figures 3-1 through 3-12) showing exact pin mappings for each configuration.

Can the D-SOIC-ADAPTER-EVM be used with op amps that have a shutdown (SD) pin?

Yes-the D-SOIC-ADAPTER-EVM supports shutdown-capable op amps on specific sections: B (X2QFN-RUG), C (WSON-DSG), and D (WSON-DRG) include auxiliary pads for 0402 resistors to tie SD pins to V+ or V−. Sections E–J (SOT-23, SC70, X2SON, SOT-5X3, WSON-DSE) are intended for non-shutdown variants only, as confirmed by TI's SBOU289 documentation for D-SOIC-ADAPTER-EVM.
