The PGA309EVM key hardware consists of two boards, PGA309 Sensor Interface Board and PGA309 PC Interface Board. The PGA309 Sensor Interface Board contains the PGA309, external SOT23-5 EEPROM, and several jumpers for ease of bridge sensor configuration. The PGA309 PC Interface Board contains an RS-232 serial interface, a 3V/5V programmable linear regulator, a switch for power control to the PGA309 Sensor Interface Board, both One-Wire and Two-Wire interface configuration and control logic, and an A/D Converter (ADS1100).
The PGA309EVM-US (USA & Canada Only) contains an AC wall adapter (120Vac to 6Vdc) to provide 6Vdc to the PGA309 PC Interface Board. For PGA309EVM-EU (Worldwide) an alternate connection on the PGA309 PC Interface Board is provided for connection to a 6Vdc (6Vdc-10Vdc) lab supply.
The PGA309EVM is designed to allow the user to attach his sensor to the PGA309 Sensor Interface Board and place this combination in a temperature chamber. By controlling the applied pressure to the pressure sensor and the temperature of the temperature chamber, the PGA309 + Sensor combination can be calibrated for optimum end module accuracy. The PGA309 Sensor Interface Board is rated for operation from -40°C to +125°C. Power, ground, output and digital interface wires connect the PGA309 Sensor Interface Board in the temperature chamber to the external PGA309 PC Interface Board. The PGA309 PC Interface Board communicates to a test computer through a standard RS-232 serial port via the PGA309DK PC Cable. The on-board A/D Converter, ADS1100, on the PGA309 PC Interface Board allows for easy reading of the analog output of the PGA309.
The PGA309EVM Software is comprised of two parts. The Board Control Software contains all of the interface and controls for communication to the PGA309 through the PGA309 PC Interface Board. It allows for reading and writing to all registers in the PGA309 as well as reading and writing to the external SOT23-5 EEPROM. Both Two-Wire and One-Wire communication options are available. In addition configuration of the PGA309 PC Interface Board and read-back of the ADS1100 is provided. The PGA309 Calibration Spreadsheet for Microsoft™ Excel provides a useful tool to calculate optimum temperature coefficients for the PGA309 + Sensor calibration based on real-world measurements of pressures at different temperatures. The PGA309 Calibration Spreadsheet also contains Visual Basic for Applications code that allows its integration with the Board Control Software. These macros allow the user to exchange PGA309 settings between the program and the spreadsheet and save the resulting EEPROM configuration file.
