NOTE: The RJA package has thicker package height compared to the RMH package. There are also four corner pins on the RJA

package. These features help to improve solder-joint reliability. The corner anchor pins and thermal pad should be soldered for robust

mechanical performance and should be tied to the appropriate ground signal. The RJA package is recommended for new product

designs.
