Replacement verdict
Compatible functional replacement candidate
The ADS1100A3IDBVRG4 is a viable functional replacement candidate for the ADS1110A0IDBVR, sharing the same I2C interface, SOT-23-6 package, and 16-bit delta-sigma architecture, though the differing gain configuration and sample rate require validation against the target application's signal range and timing requirements.

Key electrical and mechanical differences between the two devices
| Parameter | ADS1110A0IDBVR | ADS1100A3IDBVRG4 | 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 or differential) | 1 (single-ended or differential) | Channel count determines how many signals can be measured; both support one differential input. |
| Programmable Gain Amplifier (PGA) Settings | 1, 2, 4, 8 | 1, 2, 4, 8 | PGA gain ranges allow scaling of small input signals; identical gain options preserve measurement flexibility. |
| Data Rate (SPS) | 15, 30, 60, 240 | 8, 16, 32, 128 | Output data rate affects conversion speed and noise performance; the two parts offer different rate sets, impacting throughput and filtering. |
| Supply Voltage Range | 2.7 V to 5.5 V | 2.7 V to 5.5 V | Supply range determines compatibility with system power rails; both support 2.7 V to 5.5 V operation. |
| Interface | I2C | I2C | Both use I2C, so bus compatibility and addressing scheme are consistent for drop-in communication design. |
| Package | SOT-23-6 | SOT-23-6 | Package footprint affects PCB layout and assembly; identical SOT-23-6 packages allow direct board replacement. |
| Internal Reference | Yes (on-chip) | Yes (on-chip) | An internal reference simplifies design and improves accuracy; both integrate a reference, reducing external components. |
| Operating Temperature Range | -40°C to +85°C | -40°C to +85°C | Temperature range defines environmental robustness; both cover the industrial range for reliable operation. |

Frequently asked questions
What are the key differences between the ADS1110A0IDBVR and the ADS1100A3IDBVRG4?
The ADS1110A0IDBVR is a 16-bit delta-sigma ADC with a fixed PGA gain of 1 and a factory-programmed I2C address, while the ADS1100A3IDBVRG4 is a 16-bit delta-sigma ADC with a selectable PGA gain of 1, 2, 4, or 8 and a different factory-programmed I2C address. Both are single-channel devices in SOT-23-6 packages, but the ADS1100A3IDBVRG4 is supplied in a green (RoHS-compliant) molding compound per the G4 suffix.
Are the ADS1110A0IDBVR and ADS1100A3IDBVRG4 pin-compatible?
Yes. Both devices are offered in the same 6-pin SOT-23 (DBV) package with the same pin functions: VDD, GND, SDA, SCL, and the differential analog inputs VIN+ and VIN-. This allows a common PCB land pattern, but electrical differences must still be validated before substitution.
What are the resolution and data rate specifications of these two ADCs?
Both the ADS1110A0IDBVR and ADS1100A3IDBVRG4 are 16-bit delta-sigma ADCs. The ADS1110 supports programmable data rates of 8, 16, 32, and 128 SPS, while the ADS1100 supports 8, 16, 32, and 128 SPS as well. Both devices integrate an on-chip oscillator and reference, so no external clock or reference is required.
How do the PGA gain options differ between the ADS1110A0IDBVR and ADS1100A3IDBVRG4?
The ADS1110A0IDBVR has a fixed PGA gain of 1, giving a full-scale input range of ±2.048 V. The ADS1100A3IDBVRG4 offers a selectable PGA gain of 1, 2, 4, or 8, allowing full-scale ranges of ±2.048 V, ±1.024 V, ±0.512 V, and ±0.256 V respectively. The gain is selected via the configuration register over I2C.
What I2C addresses do these devices use, and can they share a bus?
The ADS1110A0IDBVR has a factory-programmed I2C address of 1001000 (0x48). The ADS1100A3IDBVRG4 has a factory-programmed I2C address of 1001011 (0x4B). Because the addresses differ, both devices can coexist on the same I2C bus without address conflict, provided bus loading and pull-up requirements are met.
What are the supply voltage and current consumption specifications?
Both devices operate from a single supply of 2.7 V to 5.5 V. The ADS1110A0IDBVR typically draws 240 µA during conversion, while the ADS1100A3IDBVRG4 typically draws 90 µA during conversion. Both feature a power-down mode that reduces supply current to typically 1 µA or less when not converting.
Are these devices RoHS-compliant and what does the G4 suffix mean?
The ADS1110A0IDBVR is supplied in a standard SOT-23-6 package. The ADS1100A3IDBVRG4 carries the G4 suffix, which indicates green molding compound and RoHS compliance per Texas Instruments' green material designation. Designers should confirm the specific environmental compliance requirements of their application against the respective datasheet and manufacturer declaration.
Can the ADS1100A3IDBVRG4 directly replace the ADS1110A0IDBVR in an existing design?
Not without validation. Although the packages and pinouts match, the I2C addresses differ (0x48 vs 0x4B), the PGA gain options differ (fixed gain 1 vs selectable 1/2/4/8), and the supply current differs. Firmware that assumes the ADS1110 address and fixed gain will not operate correctly with the ADS1100A3IDBVRG4 without modification and re-verification against the datasheet.
