The post-calibration
results will typically have
errors less than 0.1%.
The
PGA309 RatioMetric Error
tab on
the
generate_sim_values.xls
is a
convenient way to do a post-calibration
error analysis. To use it, select the
blue cell corresponding to the current
setup, and press the
Insert Vout
reading in active cell
button. This will
insert the PGA309 output reading from
the ADS1100. This spreadsheet page
provides for error calculations at two
different power supply voltages. The
initial supply is Vs= 4.963V (you need
to enter your measured Vs).
