Input Bandwidth
The ADC’s input tracking circuitry has a 4MHz small-
signal bandwidth, so it is possible to digitize high-
speed transient events and measure periodic signals
with bandwidths exceeding the ADC’s sampling rate by
using undersampling techniques. To avoid aliasing of
unwanted high-frequency signals into the frequency
band of interest, use anti-alias filtering.
Analog Input Protection
Internal protection diodes, which clamp the analog
input to AVDD or AGND, allow the input to swing from
AGND - 0.3V to AVDD + 0.3V, without damaging the
device.
If the analog input exceeds 300mV beyond the sup-
plies, limit the input current to 10mA.
