Product details

The ADS1110A3IDBVR is a 16-bit Sigma-Delta ADC from Texas Instruments, sampling at 240 SPS over an I²C interface with a built-in programmable gain amplifier (PGA) and selectable I²C address.

240 SPS and 16 bits — the measurement ceiling

Sampling at 240 SPS with 16-bit resolution, this ADC suits DC and low-frequency signals. The built-in PGA lets you amplify small differential signals before conversion, saving an external op-amp stage. Single-ended or differential input mode is configurable through the I²C registers.

SOT-23-6 footprint and I²C bus loading

Housed in a 6-pin SOT-23 package, it takes minimal board area. The selectable I²C address allows up to eight devices on the same bus. The I²C interface supports standard and fast mode.

Sourcing an obsolete ADC

For new designs, consider the active-production ADS1110 family siblings with the same footprint and I²C protocol — verify the address bits match your bus assignment.
