Settling Time of AD7767?

Hi,

 

I am confused by information in data sheet.

On page 4 (footer) it is written: "Digital Fliter Response - Settling time (latency): 74/ODR µs".

What latency for 32kHz output rate?

74/32= 2.3 µs or 2.3 ms?

 

How about the step-response? Is there any info available? I am intersted in the amount of overshoot.

 

I want to rectagle-AC excite a resistive bridge, amplify that signal, convert it and then "rectify" digitally the output words.

To achieve good line- and pink noise suppression, I thougt of 100 - 300 Hz chopping frequency.

Is this converter a good choice for that?
