There are a number of filter options for the AD7175-2 – which one should I use?
There are three power modes in AD7124-8. Which power mode should I use?
Thermal characteristics (Theta data; Max temp; Max power dissipation)
thermal data
Time required to settle after a step change in the input
What are the reference options available for the AD7961?
What are the target markets/applications for this product?
What are the tradeoffs in performance between the three power modes of AD7124-8?
What does the MUX_IO bit do on the AD7175-2?
What is a power consumption of AD2S1200?
What is AD7961?
What is ADAS3023?
What is the benefit of the post filters versus the standard sinc filters?
What is the difference between performance range and full scale range of the AD7403?
What is the ESD rating of the AD7124-8?
What package is this part offered in?
What power supplies does the AD7961 require? Does it power down?
When /CS is high, is DOUT is in tri-state mode
Why AD2S1200 pin20 toggling with /RDVEL low and Resolver stationary?
Why after every conversion of AD7091R is the MSB of the conversion result always “0”?
Why do the AD7606 pins in the "Typical Connection Diagram" such as RANGE, /STDBY have resistors and what values should they be?
Why has the power consumption of the AD7403 increased when compared to the AD7401A? 17mA typical at 20MHz and Vdd1 = 5.5V for the AD7401A and 42mA typical for the same conditions for the AD7403
Why the AD7091R ,when I measure the Idrive current during operational mode do I get higher than the 20uA as quoted in the maximum rating in the data sheet?
Why when I measure the Idd current during operational mode do I get higher than the 554uA as quoted in the maximum rating in the data sheet?
Will the AD7793 ADC continue to sample when the CS is disabled?
Working with true differential input precision SAR ADCs
Making the Interface more robust
Q
Are there any precautions that should be taken to make the interface more
robust?
A
The AD7176-2 has optional CRC protection for the interface so turning this on
will make the interface more robust. Using CS will also make the interface more
robust as when CS goes high the serial interface is set to a known state and
any interference whilst CS is high will be ignored.
