PGAxxxEVM-037 Pressure Sensor Signal Conditioner
The PGAxxxEVM-037 provides a platform to test the PGA902, PGA904, and PGA302 in the TSSOP
package. The EVM comes shipped as the PGA902EVM-037, the PGA904EVM-037, or the PGA302EVM-
037, with the name indicating the associated device included with the EVM. The PGA902EVM-037 and
PGA904EVM-037 includes a TSSOP socket, and can be used interchangeably for all three devices. This
user's guide describes both the EVM hardware platform, and the graphical user interface (GUI) software
used to configure and calibrate the PGAxxx pressure devices.
