Replacement verdict
Compatible functional replacement candidate
The ADS1110A0IDBVR and ADS1110A3IDBVR are functionally interchangeable 16-bit delta-sigma ADCs sharing the same SOT-23-6 package, I2C interface, and pinout; the only distinction is the factory-programmed I2C slave address, so the correct variant must be selected to avoid bus address conflicts in a given design.

Key electrical and mechanical differences between the two devices
| Parameter | ADS1110A0IDBVR | ADS1110A3IDBVR | Why it matters |
|---|---|---|---|
| Manufacturer | Texas Instruments | Texas Instruments | Same manufacturer ensures consistent quality and documentation, but this alone does not determine substitutability. |
| Resolution | 16 bits | 16 bits | Bit resolution determines the smallest measurable signal change; identical resolution means comparable measurement precision. |
| Input Type | Differential | Differential | Differential inputs reject common-mode noise; matching input topology is essential for drop-in compatibility. |
| Interface | I2C | I2C | The digital interface must match the host bus; both using I2C allows the same firmware and bus wiring. |
| Supply Voltage Range | 2.7 V to 5.5 V | 2.7 V to 5.5 V | Compatible supply range ensures the part operates in the same system power domain without redesign. |
| Package / Mounting | SOT-23-6, Surface Mount | SOT-23-6, Surface Mount | Identical package and mounting allow the same PCB footprint and assembly process. |
| Operating Temperature Range | -40°C to +85°C | -40°C to +85°C | Matching temperature ratings confirm both parts suit the same environmental conditions. |
| Gain / PGA Setting | PGA = 1 (A0 variant) | PGA = 8 (A3 variant) | The programmable gain setting differs between variants, changing the input voltage range and full-scale resolution, so the two are not directly interchangeable without firmware or range adjustment. |
| Full-Scale Input Range | ±2.048 V (PGA=1) | ±0.256 V (PGA=8) | Different full-scale ranges mean the measurable signal span differs, directly affecting which sensor or signal levels each variant can digitize. |
| Data Rate | 15 SPS to 240 SPS (selectable) | 15 SPS to 240 SPS (selectable) | Identical selectable output data rates mean the same sampling speed and noise/throughput trade-offs are available. |

Frequently asked questions
What is the difference between the ADS1110A0IDBVR and the ADS1110A3IDBVR?
The ADS1110A0IDBVR and ADS1110A3IDBVR are both 16-bit delta-sigma ADCs from Texas Instruments in a SOT-23-6 package, but they differ in their factory-programmed I2C slave addresses. The A0 variant has a 7-bit I2C address of 1001000 (0x48), while the A3 variant has a 7-bit I2C address of 1001011 (0x4B). This allows multiple devices to share the same I2C bus without address conflicts.
Are the ADS1110A0IDBVR and ADS1110A3IDBVR functionally identical apart from the I2C address?
Yes. Both devices share the same core specifications: 16-bit resolution, on-board PGA (gain 1 to 8), internal 2.048 V reference, internal oscillator, programmable data rate of 15 SPS to 240 SPS, and a single-ended input with a supply range of 2.7 V to 5.5 V. The only documented difference is the I2C slave address.
Can the ADS1110A0IDBVR and ADS1110A3IDBVR be used on the same I2C bus?
Yes. Because the A0 variant uses I2C address 0x48 and the A3 variant uses 0x4B, both can coexist on the same I2C bus and be addressed independently by the host controller.
What is the resolution and data rate of the ADS1110A0IDBVR and ADS1110A3IDBVR?
Both devices provide 16-bit resolution with no missing codes and support programmable data rates of 15 SPS, 30 SPS, 60 SPS, and 240 SPS, selectable via the configuration register.
What supply voltage and input range do the ADS1110A0IDBVR and ADS1110A3IDBVR support?
Both devices operate from a single supply of 2.7 V to 5.5 V and feature an on-board PGA with selectable gains of 1, 2, 4, and 8, allowing differential input ranges of ±2.048 V, ±1.024 V, ±0.512 V, and ±0.256 V respectively, referenced to the internal 2.048 V reference.
Are the ADS1110A0IDBVR and ADS1110A3IDBVR pin-compatible and package-compatible?
Yes. Both are offered in the same SOT-23-6 (DBV) package with identical pin functions, so they are pin-to-pin and footprint compatible. Substitution between them only requires updating the I2C address in firmware.
What is the operating temperature range of the ADS1110A0IDBVR and ADS1110A3IDBVR?
Both variants are specified for an operating temperature range of -40°C to +125°C, as documented in the Texas Instruments ADS1110 datasheet.
