TI ADS7870 A to D conversion

[Stanfi]

I have an existing componet that uses an ADS7870 A to D converter chip. It is desired to have an A to D with a higher resolution. What are the odds of another chip existing that would be a direct replaced with a higher resoultion? Literally un-solder the ADS7870 and install the new chip in it's place?

Thanks

In my intial research it appears a ADS7871 chip might interchange????
