Nominal voltages must have amplitudes
greater than 100mV peak at voltage ADCs
See Note
Instantaneous reading accuracy over a
dynamic range of 1000 to 1 for harmonics of
frequencies within the pass band; after the
initial 750msec settling time; PGA=1.
Accuracy over a dynamic range of 2000:1 for
harmonics of frequencies within the pass
band; average of 10 readings at 128msec
update rate, after the initial 750msec setting
time; PGA=1.
