Replacement verdict
Compatible functional replacement candidate
The ADS1110A0IDBVR and ADS1110A6IDBVR 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 | ADS1110A6IDBVR | Why it matters |
|---|---|---|---|
| Resolution | 16 bit | 16 bit | Both devices provide 16-bit resolution, so measurement precision is equivalent. |
| Programmable Gain Amplifier (PGA) Settings | 1, 2, 4, 8 | 1, 2, 4, 8 | Identical gain options allow the same input voltage ranges to be measured on both parts. |
| Full-Scale Input Range (at gain = 1) | ±2.048 V | ±2.048 V | Same full-scale range means the same maximum measurable differential input voltage. |
| Data Rate | 15 SPS to 240 SPS (selectable) | 15 SPS to 240 SPS (selectable) | Identical selectable data rates support the same sampling speed requirements. |
| Supply Voltage Range | 2.7 V to 5.5 V | 2.7 V to 5.5 V | Same supply range allows drop-in use in the same power rail designs. |
| Interface | I2C (2-wire) | I2C (2-wire) | Both use I2C, so the same bus and firmware protocol can be reused. |
| I2C Address | 1001000 (0x48) | 1001001 (0x49) | Different I2C addresses affect bus addressing and whether the parts can coexist on the same bus. |
| Package | SOT-23-6 | SOT-23-6 | Same package footprint enables direct PCB replacement without layout changes. |
| Operating Temperature Range | -40 °C to +85 °C | -40 °C to +85 °C | Identical temperature ratings ensure equivalent environmental robustness. |

Frequently asked questions
What is the difference between the ADS1110A0IDBVR and the ADS1110A6IDBVR?
The ADS1110A0IDBVR and ADS1110A6IDBVR are both 16-bit delta-sigma ADCs from Texas Instruments in the same SOT-23-6 package, but they differ in factory-programmed I2C address and PGA gain configuration. The A0 variant has I2C address 1001000 and a fixed gain of 1, while the A6 variant has I2C address 1001001 and a fixed gain of 8. These differences affect bus addressing and input voltage range, not the core conversion architecture.
Are the ADS1110A0IDBVR and ADS1110A6IDBVR pin-compatible?
Yes. Both devices are offered in the same 6-pin SOT-23 (DBV) package with identical pin functions: VDD, GND, SCL, SDA, VIN+, and VIN-. The pinout is the same, so PCB land pattern compatibility is maintained; however, the different I2C address and gain settings mean they are not drop-in functional substitutes without firmware and signal-range review.
What I2C addresses do the ADS1110A0IDBVR and ADS1110A6IDBVR use?
The ADS1110A0IDBVR uses the 7-bit I2C address 1001000 (0x48), and the ADS1110A6IDBVR uses the 7-bit I2C address 1001001 (0x49). This allows both variants to coexist on the same I2C bus without address conflict, provided the bus supports both addresses.
What PGA gain settings are factory-programmed in the ADS1110A0IDBVR and ADS1110A6IDBVR?
The ADS1110A0IDBVR is factory-configured with a PGA gain of 1, giving a full-scale input range of ±2.048 V. The ADS1110A6IDBVR is factory-configured with a PGA gain of 8, giving a full-scale input range of ±0.256 V. The gain setting is fixed at production and cannot be changed by the user.
Do the ADS1110A0IDBVR and ADS1110A6IDBVR share the same resolution and data rate?
Yes. Both are 16-bit delta-sigma ADCs with a programmable output data rate of 15, 30, 60, or 240 samples per second, and both include an on-chip oscillator, reference, and PGA. The resolution, data rate options, and internal reference are identical across the two variants.
Can the ADS1110A0IDBVR and ADS1110A6IDBVR operate from the same supply voltage?
Yes. Both variants operate from a single supply of 2.7 V to 5.5 V and are specified for the same supply range. The supply voltage requirement does not differ between the A0 and A6 versions.
When should the ADS1110A6IDBVR be chosen over the ADS1110A0IDBVR?
The ADS1110A6IDBVR should be selected when the measured signal is small and benefits from the higher PGA gain of 8, which provides a ±0.256 V full-scale range and improved resolution for low-level inputs. The ADS1110A0IDBVR is appropriate for larger signals up to ±2.048 V full scale. Selection should be based on the expected input signal amplitude and the required I2C address on the bus.
