PGAxxxEVM-037 Pressure Sensor Signal Conditioner Evaluation Module
When making changes to any parameters on the PGA302 EEPROM settings page, the new settings are
automatically burned to the EEPROM. No separate programming action is required. However, it is
necessary to update the CRC once any of the EEPROM settings have been changed, including at the end
of a calibration procedure.
4.13.1
Linearity Calibration Parameters
The linearity calibration parameters are automatically set once the
Linearity Calibration Procedure
(see
) has been completed. No user input is necessary; however, individual coefficients can be
changed manually if desired.
4.13.2
Analog Front End Settings
The
Analog Front End Settings
are the same as those included in the
Analog Front End
block diagram
panel. To program the settings in the EEPROM, they must be entered in the
PGA302 EEPROM Settings
panel. For a full description of the Analog Front End Settings, see
4.13.3
DAC Output Settings
The DAC Output Settings allow the user to configure the DAC output ranges as well as the DAC output
level during a fault.
4.13.4
Diagnostics Enable
Allows the user to enable analog front end diagnostic bits to be viewed in the
Fault Status
tab. See
for a description of diagnostic bits.
4.13.5
Other Settings
Other settings on this page include locking the EEPROM so that the values cannot be changed, enabling
all diagnostics with a single check box, viewing the production serial number of the PGA302 device (read
only), or setting the
IIR Filter Cutoff
frequency.
