Figure 21: PGA309 Registers – Main Window
7.4 PGA Settings
Rather than toggling individual bits of the registers described above, the PGA309 can be configured using
drop-down menu selections or check-boxes in the “PGA Settings” section of the Main Window contains:
Coarse Offset (mV)
FrontEnd PGA Gain (V/V)
Zero DAC (V)
Gain DAC (V/V)
Output Amp Gain (V/V)
Enable Over/Under-Scale Limits
Overscale Limit
Underscale Limit
Enable Sensor Excitation
Linearization Coef (V/V)
Enable Internal Vref
Vref Value
Changing these settings will update the corresponding bits of in the register table and vice versa. The current
values of these and the PGA309 registers will be automatically updated in the Main Window following a “Read
PGA309”. The current settings displayed in the Main Window will be written to the PGA309 internal registers
following a “Write PGA309” or to the external PGA309 EEPROM following a “Write EEPROM”. If the “Instant
Update” check-box in the lower right of the Main Window is checked then the PGA309 internal registers will
automatically be updated after every change. Remember if you do not want the register settings in the
PGA309 to be over-written by valid PGA309 external EEPROM data then ensure the PGA309 Test pin is set
high by checking the “PGA309 Test Pin HIGH” box in the upper left area of the Main Window.
