Good morning,
I want to use the ad7277 to digitize the output of an analog current integrator. For simplicity, I want to use the CS (chip select) input of the ADC also to reset the current integrator output to zero (by discharging the capacitor with…
Hi sss,
The timing specification on table 5 is applicable on AD7276/AD7277/AD7278 unless it is otherwise noted that it is only on a specific part. The T3 which is 4ns(min), although not mentioned on figure 35, it is also applicable in the 10 SCLK Cycle…
From the SAR space I would recommend either the AD7276/77 or the AD7482. The two parts are at 3MSPS, single channel, single ended. The AD7277 is a 10 bit version of the AD7276. The AD7276 is serial whereas the AD7482 is parallel. These are currently the…
Sean, This has been a very interesting journey so far, and we are still working this problem. One of the angles we are exploring has to do with layout, grounding, and noise isolation.
Regarding layout, and looking at the AD7276 evaluation board docs online…
In Rev B of the datasheet for the AD7276, AD7277, AD7278 , on page , there is an error within fig 21 where the LSB sizes for the AD7276 and AD7278 is reversed.
It is properly described in the text above the figure.
