AD7989 is a true differential ADC.I recommend these pseudo differential ADC see attached .http://www.analog.com/AD7680?doc=ad7989-1_7989-5.pdf, http://www.analog.com/AD7683?doc=ad7989-1_7989-5.pdf, http://www.analog.com/AD7988-1?doc=ad7989…
Is AD7989 has Branding C7P ? Please help by replying
The power of ad7989-5 must be 2.5V? i use 3.3V, and then i use single mode directly ,the result is that if ain+ is under 2.0v, the adc out is wrong, how to solve the problem on pcb board?, 3.3V or single mode？
On the AD7989-5 data sheet it is mentioned that the total power dissipation is 3.5 mW at 500 kSPS.
On the web page http://www.analog.com/en/products/analog-to-digital-converters/ad7989-5.html#product-overview it is mentioned 3.5 μW.
I assume that…
AD7989 will be used to collect sensor signal and then data will be correlated with a reference fequence base to detect very weak signal.Normally the sampling clock should be derived from the same clock source as correlated fequence base.With AD7989-5…
Apologies for the delayed response.
I'd recommend a newer ADC such as the AD7989-1, an 18-bit part with the same throughput as AD7684. You might also want to check the 16-bit AD7916 that has higher throughputs. The best place in the signal…
On the ADI website you can do a parametric search where you can select the specification that you wanted and short list product that fits your application. By the way what is your application? What type of data are you coolecting for the ADC? and…
