Other Parts Discussed in Thread: ADS1220,
Hello E2E Experts,
1. Can you recommend a method to find out in software if the 16bit ADC "ADS1120" or the pin-compatible 24bit ADC "ADS1220" is installed on a PCB?
2. The ADS1120 is unavailable at my usual distributors (mouser.de, digikey.de, farnell.de and de.rs-online.com). US distributors such as Arrows refuse to ship to a me (freelancer without VAT idenfication number). I therefore bought a few ADS1x20 from China's Aliexpress. They did cost less than TI's pricing, which was strange. Do you know if the masses of cheap "original" ADS1x20 chips on Aliexpress are genuine or is that a chesspit of inferior fakes?
