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 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…
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…
Is AD7989 has Branding C7P ? Please help by replying
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…
can you suggest any way to produce +-5 from +5.I need it for one 4ch differential signal summer op-amp plus salen-key filter op-amp.
Is there any DC/DC converter or something in ADI that doing this?
