Replacement verdict
Compatible functional replacement candidate
The ADS1110A1IDBVR is a functional upgrade candidate for the ADS1100A1IDBVR, sharing the same SOT-23-6 footprint, 16-bit delta-sigma architecture, and I2C interface, while offering a wider programmable gain range and higher output data rate. Designers should validate supply voltage headroom, PGA configuration, and data-rate timing against the target application before substituting.

Key electrical and mechanical differences between the two devices
| Parameter | ADS1100A1IDBVR | ADS1110A1IDBVR | Why it matters |
|---|---|---|---|
| Resolution (bits) | 16 | 16 | Both are 16-bit delta-sigma ADCs, so resolution is equivalent for precision measurement applications. |
| Input Channels | 1 (single-ended/differential) | 1 (single-ended/differential) | Both provide a single input channel, limiting them to one measurement path per device. |
| Interface | I2C | I2C | Both use I2C, so they are drop-in compatible for the same bus architecture. |
| Programmable Gain Amplifier (PGA) | Yes (gain 1 to 8) | Yes (gain 1 to 8) | On-chip PGA allows small signals to be amplified, improving effective resolution for low-level inputs. |
| Data Rate (SPS) | 8 to 128 | 15 to 240 | The ADS1110 offers higher maximum sample rates, enabling faster conversions where throughput matters. |
| Supply Voltage Range | 2.7 V to 5.5 V | 2.7 V to 5.5 V | Identical supply range means both work in the same 3.3 V and 5 V systems. |
| Package | SOT-23-6 | SOT-23-6 | Same package footprint allows direct board-level substitution without layout changes. |
| Internal Reference | Yes (on-chip) | Yes (on-chip) | Integrated reference reduces external component count and simplifies design. |
| Operating Temperature Range | -40 °C to +85 °C | -40 °C to +85 °C | Identical temperature ratings ensure both suit the same industrial environments. |

Frequently asked questions
What are the key differences between the ADS1100A1IDBVR and ADS1110A1IDBVR?
Both are 16-bit delta-sigma ADCs in SOT-23-6 packages with I2C interfaces, but they differ in input configuration and programmable gain. The ADS1100 is a single-channel device with selectable gains of 1, 2, 4, and 8, while the ADS1110 is also single-channel but offers gains of 1, 2, 4, and 8 with an on-chip PGA and supports a wider data rate range. The ADS1110 provides programmable data rates from 15 SPS to 240 SPS, whereas the ADS1100 offers 8 SPS, 16 SPS, 32 SPS, and 128 SPS. Designers should verify the exact gain and data-rate requirements against the respective datasheets.
Are the ADS1100A1IDBVR and ADS1110A1IDBVR pin-compatible?
Yes, both devices are offered in the same 6-pin SOT-23 (DBV) package and share a compatible pinout for VDD, GND, SCL, SDA, and analog input connections. However, pin function assignments and internal register maps differ, so firmware and configuration must be validated before substituting one for the other.
What is the resolution and architecture of these ADCs?
Both the ADS1100A1IDBVR and ADS1110A1IDBVR are 16-bit delta-sigma analog-to-digital converters with a single-ended input configuration and an on-chip programmable gain amplifier. They are designed for low-power, high-resolution measurement applications.
What I2C addresses do the ADS1100A1IDBVR and ADS1110A1IDBVR use?
The ADS1100 supports I2C addresses selectable via the ADDR pin, and the ADS1110 uses a fixed I2C address determined by the device variant. The "A1" suffix in both part numbers denotes a specific I2C address option. Designers should confirm the exact address from the respective manufacturer datasheet before bus integration.
What are the supply voltage and power consumption specifications?
Both devices operate from a single supply in the 2.7 V to 5.5 V range and are specified for low-power operation. The ADS1100 typically consumes around 90 µA in continuous conversion mode, while the ADS1110 consumes approximately 240 µA. Exact quiescent and conversion currents should be verified from the official datasheets for the specific operating conditions.
Can the ADS1100A1IDBVR and ADS1110A1IDBVR be used interchangeably in an existing design?
They are not drop-in replacements without validation. Although they share the same package and 16-bit delta-sigma architecture, differences in data rate options, register configuration, I2C addressing, and power consumption require firmware and hardware review. A substitution should only be made after confirming compatibility against both manufacturer datasheets.
What data rates are supported by each device?
The ADS1100 supports programmable data rates of 8 SPS, 16 SPS, 32 SPS, and 128 SPS. The ADS1110 supports programmable data rates of 15 SPS, 30 SPS, 60 SPS, and 240 SPS. The appropriate device should be selected based on the required conversion speed and noise performance for the application.
