ADS7142: Possible error and unclear statements in ADS7142 datasheet

Part Number: ADS7142
I see multiple errors or unclear statements in ADS7142 datasheet. Some of them cause confusions and upon searching e2e forum I saw some others were bothered by them too. Probably this needs a dedicated thread and some attention.

Referring to ADS7142 datasheet Rev A (SBAS773A):

1.
In Table 6.5
Under
ANALOG INPUT- Single-Channel Pseudo-Differential Configuration
Full-scale input voltage span, "AINP/AIN0 to GND or AINM/AIN1 to GND", Minimum value is –AVDD/2?
This is lower than the lowest absolute maximum rating (GND-0.2V)
Does it in fact mean "AINP/AIN0 to AINM/AIN1" since this is the definition of differential input?

2.
In Figure 30
For 2-channel single-ended configuration, analog input channel 0 SOURCES current instead of SINKING current? Is the polarity correct?

3.
In Table 6.3
DVDD, Digital Voltage Supply Voltage Range, the unit should be V, not A

4.
In Table 6.5
Under "Digital Output (BUSY/RDY)"
VOL, "High Level Output Voltage" should be "Low Level Output Voltage"

5.
In Table 6.6, Table 6.7, and Table 6.8
Under "Power Consumption"
IDVDD "Static Analog Supply Current" should be "Static Digital Supply Current"

6.
Section 7.3.1
This is not an error, but this statement regarding "high impedance drive on input" is not worded properly and may be hard to grasp:

"The analog input of the device are optimized to be driven by high impedance source (up-to 100 kΩ) in Autonomous Modes or in High Precision Mode mode with low power oscillator."

I saw it caused confusion to some people as can be seen in this thread:
e2e.ti.com/.../819826
As asked by the original poster, why do you need a high impedance source to drive the ADC input?
And also the TI employee answered the question wrong:
"When in autonomous mode, it is recommended that the input is driven by a high impedance source, usually an op amp."

No, op amp has low output impedance, and this is neither the correct answer nor a good explanation to the original poster's circuit problem.

I think here's a more clear way to say it in datasheet:
"In many ADC designs, the common choice is driving the ADC input with a low-impedance source. But for ADS7142, the analog inputs are capable of, and optimized for, being driven by higher impedance sources (up to 100 kΩ), when the device operates in Autonomous Modes or in High Precision Mode mode with low power oscillator. This advantage may eliminate the need of using a low output impedance buffer amplifier as ADC driver, saving cost and reducing power consumption in design.
When in Autonomous Modes or in High Precision Mode mode with High Speed oscillator, however, it is still recommended to drive the analog input with a low-impedance source such as external amplifier."

Thanks.
