16-bit precision in a SOT-23-6 package
The ADS1110A2IDBVTG4: 16-bit sigma-delta ADC with a single differential or single-ended input sampling at 240 SPS.
I²C bus with selectable address
Communication runs over a standard I²C interface, and the A2 in the order code indicates a factory-programmed I²C address, letting you place up to four of these on the same two-wire bus without address collisions. The PGA gives programmable gains of 1, 2, 4, or 8 — useful for amplifying small sensor signals before the sigma-delta modulator, keeping the noise floor low.
