Replacement verdict
Compatible functional replacement candidate
The ADS1110A1IDBVR is a viable functional replacement candidate for the ADS1100A0IDBVR, sharing the same I2C interface, SOT-23-6 package, and 16-bit delta-sigma architecture, though the higher programmable gain and faster data rate of the ADS1110A1IDBVR require validation against the target application's input range and timing requirements.

Key electrical and mechanical differences between the two devices
| Parameter | ADS1100A0IDBVR | ADS1110A1IDBVR | Why it matters |
|---|---|---|---|
| Resolution (bits) | 16 | 16 | Both are 16-bit delta-sigma ADCs, so resolution alone does not differentiate them for substitutability. |
| Input channels | 1 (single-ended/differential) | 1 (single-ended/differential) | Channel count determines how many signals can be measured; both support a single differential input. |
| Programmable gain amplifier (PGA) settings | 1, 2, 4, 8 | 1, 2, 4, 8 | PGA gain ranges set the full-scale input voltage and affect measurement of small signals; identical here. |
| Data rate (SPS) | 8, 16, 32, 128 | 15, 30, 60, 240 | Output data rate affects conversion speed and noise; the two parts offer different selectable rates, impacting timing-critical designs. |
| Supply voltage range | 2.7 V to 5.5 V | 2.7 V to 5.5 V | Supply range determines compatibility with system rails; both operate over the same 2.7–5.5 V span. |
| Interface | I2C | I2C | The digital interface must match the host bus; both use I2C, simplifying drop-in replacement. |
| Package | SOT-23-6 | SOT-23-6 | Package footprint affects PCB layout and assembly; identical SOT-23-6 packages allow the same land pattern. |
| Internal reference | No (ratiometric) | Yes (internal 2.048 V) | An internal reference provides absolute measurement accuracy independent of supply, while a ratiometric part depends on the supply as reference. |
| Operating temperature range | -40 °C to +85 °C | -40 °C to +85 °C | Temperature range defines environmental limits; both cover the same industrial-grade span. |

Frequently asked questions
What are the key differences between the ADS1100A0IDBVR and ADS1110A1IDBVR?
The ADS1100A0IDBVR is a 16-bit delta-sigma ADC with a fixed gain of 1 and a single differential input, while the ADS1110A1IDBVR is also a 16-bit delta-sigma ADC but includes an on-chip PGA with a gain of 1 and a single differential input. Both are offered in a SOT-23-6 package and communicate over I2C, but the ADS1110A1IDBVR integrates a programmable gain amplifier and a voltage reference, whereas the ADS1100A0IDBVR relies on an external reference and has a fixed gain of 1.
Are the ADS1100A0IDBVR and ADS1110A1IDBVR pin-compatible?
Yes, both devices are packaged in a SOT-23-6 (DBV) package and share the same pinout, allowing for potential drop-in replacement in existing PCB layouts, provided the electrical differences are accounted for.
What are the supply voltage requirements for these ADCs?
Both the ADS1100A0IDBVR and ADS1110A1IDBVR operate from a single supply voltage ranging from 2.7 V to 5.5 V, making them suitable for low-power and portable applications.
Do these ADCs have an internal voltage reference?
The ADS1110A1IDBVR includes an internal 2.048 V voltage reference, while the ADS1100A0IDBVR does not have an internal reference and requires an external reference voltage for operation.
What is the maximum sampling rate for each device?
The ADS1100A0IDBVR offers programmable data rates of 8, 16, 32, and 128 samples per second (SPS), while the ADS1110A1IDBVR provides data rates of 15, 30, 60, and 240 SPS.
Can the ADS1110A1IDBVR be used as a direct replacement for the ADS1100A0IDBVR?
While the devices are pin-compatible, a direct replacement requires verifying that the internal reference and different data rates of the ADS1110A1IDBVR are compatible with the existing system design, and that the gain settings meet the application requirements.
What is the resolution of these ADCs?
Both the ADS1100A0IDBVR and ADS1110A1IDBVR are 16-bit delta-sigma analog-to-digital converters, providing high-resolution conversion for precision measurement applications.
