New clone on the block

While browsing for low cost EVBs, I noticed that some of the ADS1115 (4-channel 16-bit delta-sigma i2c adc) are being fitted with an IC marked ADX111A.

Which turns out to be at least on paper nearly identically to the ADS1115.

TI ADS111x

I'm not against competition. But the dark/dangerous side is when someone laser marks the chip as being TI's part, and sells it as a genuine TI part, when it most certainly isn't.

Glass half-full, glass half-empty....

Naming convention shows that it is most probably very legendary chip originaly designed by ADI and not TI. But ADI most probably deprecated it. Note that TI sometimes do clones of the chip with the same name. Some other example: https://www.ti.com/product/MAX3232

You can give a try to ADS1115 but over the years I learnt that in this situation it is much easier to switch more modern chip which is not influenced by this kind of issues yet.
