Analog Input Bandwidth
The MAX1036
–
MAX1039 feature input tracking circuitry
with a 2MHz small signal-bandwidth. The 2MHz input
bandwidth makes it 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 high fre-
quency signals being aliased into the frequency band
of interest, anti-alias filtering is recommended.
Analog Input Range and Protection
Internal protection diodes clamp the analog input to
V
DD
and GND. These diodes allow the analog inputs to
swing from (GND - 0.3V) to (V
DD
+ 0.3V) without caus-
ing damage to the device. For accurate conversions,
the inputs must not go more than 50mV below GND or
above V
DD
. If the analog input exceeds V
DD
by more
than 50mV, the input current should be limited to 2mA.
