Hi Kuramochi,
We provide similar notations as the document in page 187 as per the link below. We offer ratings on our devices but i am not sure what you mean by derating for a monolithic semiconductor.

HI Alen,
I see it forms an RC filter. That is fair.
I have not tried this approach on the bench and my bench capabilities are limited. I would still add the 1uF directly on the Out_F output due to stability.
The REF5045 also requires this capacitor…
Hello,
Thank you for your response,
I have set the SCLK duty cycle between 45% to 55% but it didn't make a difference.(As shown in figure below)
We are using 4.5 Volts reference which provided by REF5045 component. ADS8887 , OP-AMP Circuit…
Hello Shibin,
The ADS8900B includes a reference buffer, but still requires an external reference. In this case, the REF50xx is an excellent choice. Since your input is +/-4V, you can use the REF5040 (4.096V) to take advantage of the full dynamic range…
Hello Roy,
The REF6045 would be the preferred reference for the ADS8339. The external ref buffer was recommended in the datasheet because the REF60xx did not yet exist. There are a couple of cases where you may want to use the REF5045 and an external…
Hi Carl,
The REF5045 was used with the circuit shown on Figure 105 for the case when using internal buffer and a 22uF X7R grade bypass capacitor at the REFBUFOUT pin. The REF5045 without buffer was used to generate the external reference without buffer…
Hi Shmuel,
The RC filter for the reference input is optional, but a good idea to help with overall system noise. Since the output noise of the REF5045 is only specified over a bandwidth of 0.1 to 10Hz, there may be higher frequency noise that could…
Hi Cay,
The ADC161S626 is a differential input SAR ADC. The device also supports single-ended inputs, however there are bias requirements for the inverting input (IN-) and reference voltage range. When using the device in single-ended operation, the…
Hi Luis and Mo, I am now in a position to finalise my schematics. I cannot use ADS8910B because I still have to allocate 24 of the REF5045. I now want to provide a common 4.5V reference to all 24 ADCs (or 12) by implementing a single reference circuit…
