The PGAxxxEVM-034 supplies a platform to test the PGA900, PGA300, and PGA305 in the QFN
package. The EVM is shipped as either the PGA900EVM-034, the PGA300EVM-034, or the
PGA305EVM-034, with the name identifying the signal conditioner included in the EVM package. The
PGAxxxEVM-034 supplies an interchangeable platform all of these devices can use.
