Make sure that you
measure the supply voltage
(Vs) and enter it into the
PGA309 Designer’s Kit
Control Program
.
Measure the PGA309 post calibration error
at a different supply voltage to see the
affect of PSR on error. For this example,
the supply was changed from Vs= 4.963V
to Vs=4.457V and the average error
changed from -0.06% to -0.03%.
