Check the listing for details. SOIC16 TSSOP16 Black PCB Adapter Boards for SMD to DIP Panel of 25. Condition: New. Listed at 7.45 USD. We occasionally need to use a device in an SMD package to quickly prototype and verify a design, so we created these adapter boards for the more common 16-pin SO* (front 1.27mm pitch) and *SOP (back 0.65mm pitch) packages. Since we are able to panelize these boards we would like to share them at a reasonable price and hope that you can find a use for them in your projects as well. Please double check the respective package dimensions to ensure that the PCB landing pads are compatible with your IC's footprint.
