16-bit sigma-delta ADC with PGA in a SOT-23-6
The ADS1110A4IDBVTG4: It accepts a single differential or single-ended input and samples at 240 SPS. The on-chip PGA lets you amplify small sensor signals — thermocouple, strain gauge, or bridge outputs — before conversion, eliminating the external op-amp stage that a lower-integration ADC would need.
I²C address — the A4 variant's bus slot
The A4 suffix sets a fixed I²C address. The base ADS1110 family supports selectable addresses across suffix variants, allowing multiple converters on the same bus without address conflicts.
