OPAMPEVM-SOT23 Evaluation Board Texas Instruments OPAMPEVM-SOT23 Evaluation Board is a general-purpose blank circuit board that simplifies the evaluation of surface-mount op-amps without a shutdown terminal. The evaluation module board design allows many different circuits to be constructed easily and quickly. The Texas Instruments OPAMPEVM-SOT23 has four separate circuit development areas that can be snapped apart and separated. Two of the areas are designed explicitly for SOT23-5 package op-amps, and the other two areas support SOIC-8 and MSOP-10 type packages.
