RCV 420 types difference

Other Parts Discussed in Thread: RCV420

Hi,

What is the difference between the RCV420JP; RCV420KP; RCV420KPG4 & RCV420JPG4?

Technical documents and information available found else where seem to imply that they're all the same but the pricing varies considerably. 

Thanks

Varun

    Hi Varun,

    The primary difference is between the JP and KP versions of the parts, with JP being the low grade and KP being the high grade. During testing of the parts they are separated into these categories based on their performance in certain categories like gain error and initial offset error. In the datasheet performance matrix, there are separate numbers in categories where the JP's performance is lower than the KP.

    Hope this helps!

    Hi Varun,

    In addition to the RCV420 grade information provided by John there is the additional difference with JP vs. JPG4, and KP vs. KPG4. I did some checking and what I found is that the added G4 designation indicates that the product is RoHS and green package material compliant. The G4 was added during a time when the conversion from the older Pb/non-green materials were still being used to package some intergrated circuits. The unique model designations allowed customers to distinguish between devices processed using one set of materials, or the other, and order accordingly.

    Now, to the best of my knowledge, all TI products are RoHS/green compliant and that includes the RCV420JG and KG grades. Therefore, it wouldn't matter if you selected JP, or JPG4, for example.
