This permits the user to test op amps in different packages without making changes to the existing PCB. 2 How to Use The TSSOP-VSSOP-ADAPTER-EVM comes depopulated. Devices must be ordered separately. To find a specific device in a specific package, use the Find Product by Package search tool. Solder the IC(s) to the adapter PCB. Parts may be hand soldered or attached with hot air reflow techniques. Gently flex panel at score lines to separate adapter boards. Position the adapter board carefully over the footprint and solder it on.

Each adapter option has a corresponding letter on the back of the PCB to help better identify them. Table 3-1 shows each corresponding board label, package designator, TI package designator, and pin count. Table 3-1.
