Multiplexer, Conversion, and
Data Output Timing
The specified conversion time includes one or two settling and
sampling periods and a scaling time.
With chopping enabled (Figure 25), a conversion cycle starts
with a settling time of 43 MCLK cycles or 44 MCLK cycles (~7
μs with a 6.144 MHz MCLK) to allow the circuits following the
multiplexer to settle. The sigma-delta modulator then samples
the analog signals and the digital filter processes the digital data
stream. The sampling time depends on FW, i.e., on the channel
conversion time register contents. After another settling of 42
MCLK cycles (~6.8 μs), the sampling time is repeated with a
reversed (chopped) analog input signal. Then, during the
scaling time of 163 MCLK cycles (~26.5 μs), the two results
from the digital filter are averaged, scaled using the calibration
registers, and written into the channel data register.
With chopping disabled (Figure 26), there is only one sampling
time preceded by a settling time of 43 MCLK cycles or
44 MCLK cycles and followed by a scaling time of
163 MCLK cycles.
The RDY pin goes high during the scaling time, regardless of its
previous state. The relevant RDY bit is set in the ADC status
register and in the channel status register, and the RDY pin goes
low when the channel data register is updated and the channel
conversion cycle is finished. If in continuous conversion mode,
the part will automatically continue with a conversion cycle on
the next enabled channel.
Note that every channel can be configured independently for
conversion time and chopping mode. The overall cycle and
effective per channel data rates depend on all enabled
channel settings.
Sigma-Delta ADC
The AD7732 core consists of a charge balancing sigma-delta
modulator and a digital filter. The architecture is optimized for
fast, fully settled conversion. This allows for fast channel-to-
channel switching while maintaining inherently excellent
linearity, high resolution, and low noise.
