Product details

Precision 16-bit ADC in a SOT-23-6 — what it brings to a sensor front-end

It accepts a single differential or single-ended input and communicates over an I²C bus with a selectable address. The internal reference and PGA eliminate the need for external gain or reference components, making it a compact fit for precision sensor conditioning in tight board areas.

240 SPS sampling rate — built for DC and low-frequency signals

The ADS1110A4IDBVR samples at 240 samples per second (SPS). That is a deliberate trade-off: the sigma-delta architecture and internal digital filter reject 50/60 Hz line noise well, so this part is suited for weighing scales, thermocouple interfaces, pressure transducers, and other slow-changing sensor outputs where noise-free readings matter more than throughput. With 16-bit resolution and the PGA, the effective resolution at lower gains can exceed 15 bits at 240 SPS. The PGA scales small differential signals (e.g., from a bridge sensor) before conversion, preserving dynamic range without an external op-amp.

SOT-23-6 package — rework-friendly footprint

The SOT-23-6 is a standard small-outline transistor package with 0.95 mm pitch leads.

Frequently asked questions

Is the ADS1110A4IDBVR compatible with 3.3 V logic?

Yes.

What is the maximum sampling rate of the ADS1110A4IDBVR?

The maximum sampling rate is 240 samples per second (SPS). This is a fixed rate set by the internal sigma-delta modulator and digital filter.

What is the equivalent of the ADS1110A4IDBVR?

The ADS1110 family includes multiple I²C address variants (A0 through A7). The ADS1110A4IDBVR uses address 1001000. The ADS1115 is a different part — it has four inputs, a programmable data rate up to 860 SPS, and an internal voltage reference with higher accuracy, but it is not pin-compatible with the ADS1110.
