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
VDD and GND. These diodes allow the analog inputs to
swing from (GND - 0.3V) to (VDD + 0.3V) without caus-
ing damage to the device. For accurate conversions,
the inputs must not go more than 50mV below GND or
above VDD. If the analog input exceeds VDD by more
than 50mV, the input current should be limited to 2mA.
