Detailed Description
The MAX11047/MAX11048/MAX11049 and MAX11057/
MAX11058/MAX11059 are fast, low-power ADCs that
combine 4, 6, or 8 independent ADC channels in a sin-
gle IC. Each channel includes simultaneously sampling
independent T/H circuitry that preserves relative phase
information between inputs making the devices ideal for
motor control and power monitoring. The devices are
available with a 0 to 5V input range that features
±20mA overrange, fault-tolerant inputs. The devices
operate with a single 4.75V to 5.25V supply. A separate
2.7V to 5.25V supply for digital circuitry makes the
devices compatible with low-voltage processors.
The devices perform conversions for all channels in paral-
lel by activating independent ADCs. Results are available
through a high-speed, 20MHz, parallel data bus after a
conversion time of 3s following the end of a sample. The
data bus is bidirectional and allows for easy program-
ming of the configuration register. The devices feature a
reference buffer, which is driven by an internal bandgap
reference circuit (VREFIO = 4.096V). Drive REFIO with an
external reference or bypass with a 0.1F capacitor to
ground when using the internal reference.
Analog Inputs
Track and Hold (T/H)
To preserve phase information across all channels,
each input includes a dedicated T/H circuitry. The input
tracking circuitry provides a 4MHz small-signal band-
width, enabling the device to digitize high-speed tran-
sient events and measure periodic signals with
bandwidths exceeding the ADC’s sampling rate by
using undersampling techniques. Use anti-alias filtering
to avoid high-frequency signals being aliased into the
frequency band of interest.
