Replacement verdict
Compatible functional replacement candidate
The ADS1110A0IDBVR and ADS1100A1IDBVR are both 16-bit delta-sigma ADCs in the same SOT-23-6 package with an I2C interface, making them strong functional replacement candidates. The primary distinction is the factory-programmed I2C slave address (ADS1110A0 at 0x48 versus ADS1100A1 at 0x49), so the replacement is viable provided the system firmware or bus addressing is adjusted accordingly. Gain and data-rate configuration differences should also be validated against the target application before substitution.

Key electrical and mechanical differences between the two devices
| Parameter | ADS1110A0IDBVR | ADS1100A1IDBVR | Why it matters |
|---|---|---|---|
| Resolution (bits) | 16 | 16 | Both are 16-bit delta-sigma ADCs, so resolution alone does not distinguish them for substitutability. |
| Input Channels | 1 (single-ended or differential) | 1 (single-ended or differential) | Channel count and configuration determine whether the part fits the signal topology of the target design. |
| Programmable Gain Amplifier (PGA) Settings | 1, 2, 4, 8 | 1, 2, 4, 8 | PGA range affects the measurable input span and effective resolution for small signals. |
| Data Rate (SPS) | 15, 30, 60, 240 | 8, 16, 32, 128 | Output data rate sets the trade-off between conversion speed and noise; the two parts offer different rate options, affecting timing and filtering in the system. |
| Interface | I2C | I2C | Both use I2C, so bus compatibility is maintained, but address and protocol details must still be checked. |
| Supply Voltage Range | 2.7 V to 5.5 V | 2.7 V to 5.5 V | Matching supply ranges allow the parts to operate in the same power rail environment. |
| Package | SOT-23-6 | SOT-23-6 | Identical package and pinout simplify board-level substitution without layout changes. |
| Internal Reference | Yes (on-chip) | Yes (on-chip) | An internal reference reduces external component count and simplifies the analog front end. |
| Operating Temperature Range | -40 °C to +85 °C | -40 °C to +85 °C | Equivalent temperature ratings ensure both parts meet the same environmental requirements. |

Frequently asked questions
What are the key differences between the ADS1110A0IDBVR and ADS1100A1IDBVR?
Both are 16-bit delta-sigma ADCs with I2C interfaces in SOT-23-6 packages, but they differ in resolution and gain configuration. The ADS1110A0IDBVR offers a programmable gain amplifier with selectable gains of 1, 2, 4, and 8, and supports data rates of 15, 30, 60, and 240 SPS. The ADS1100A1IDBVR has a fixed gain of 1 and supports data rates of 8, 16, 32, and 128 SPS. The ADS1110A0IDBVR also includes an on-chip PGA and a wider selectable gain range, while the ADS1100A1IDBVR is limited to unity gain.
Are the ADS1110A0IDBVR and ADS1100A1IDBVR pin-compatible?
Yes, both devices are offered in the same SOT-23-6 (DBV) package and share the same pinout: VDD, GND, SCL, SDA, and the analog input pins. This allows them to be used on the same PCB footprint, but firmware and configuration settings must be adjusted because the register maps and gain/data-rate options differ.
What is the resolution of each device?
Both the ADS1110A0IDBVR and ADS1100A1IDBVR are 16-bit delta-sigma analog-to-digital converters. The ADS1110A0IDBVR provides 16-bit resolution with a programmable gain amplifier, while the ADS1100A1IDBVR provides 16-bit resolution with a fixed gain of 1.
What data rates are supported by the ADS1110A0IDBVR and ADS1100A1IDBVR?
The ADS1110A0IDBVR supports selectable data rates of 15, 30, 60, and 240 samples per second (SPS). The ADS1100A1IDBVR supports selectable data rates of 8, 16, 32, and 128 SPS. The higher maximum data rate of the ADS1110A0IDBVR makes it suitable for faster-sampling applications.
What gain options are available on each device?
The ADS1110A0IDBVR includes a programmable gain amplifier with selectable gains of 1, 2, 4, and 8, allowing it to measure small differential signals. The ADS1100A1IDBVR has a fixed gain of 1, so it does not provide PGA functionality and is limited to unity-gain measurements.
What is the supply voltage range for these ADCs?
Both the ADS1110A0IDBVR and ADS1100A1IDBVR operate from a single supply voltage of 2.7 V to 5.5 V, making them compatible with common 3.3 V and 5 V systems.
Can the ADS1100A1IDBVR be used as a drop-in replacement for the ADS1110A0IDBVR?
Because both devices share the same SOT-23-6 package and pinout, the ADS1100A1IDBVR can be placed on the same footprint. However, it is not a functional drop-in replacement: the ADS1100A1IDBVR has a fixed gain of 1 and different data-rate options, so firmware configuration and system-level performance must be revalidated before substitution.
What communication interface do these devices use?
Both the ADS1110A0IDBVR and ADS1100A1IDBVR use a two-wire I2C-compatible serial interface for configuration and data readout, supporting standard and fast-mode operation.
