Replacement verdict
Compatible functional replacement candidate
The ADS1110A6IDBVR is a functional replacement candidate for the ADS1100A0IDBVR, sharing the same SOT-23-6 package, 16-bit delta-sigma architecture, and I2C interface, but it is not a drop-in replacement because the fixed PGA gain, data rate, and supply range differ. Designers must validate gain configuration, conversion timing, and supply tolerance before substituting in existing layouts.

Key electrical and mechanical differences between the two devices
| Parameter | ADS1100A0IDBVR | ADS1110A6IDBVR | 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/differential) | 1 (single-ended/differential) | Both provide a single input channel, limiting them to one measurement path per device. |
| Programmable Gain Amplifier (PGA) Settings | 1, 2, 4, 8 | 1, 2, 4, 8 | Identical PGA ranges allow both to scale small signals similarly for low-level sensor inputs. |
| Data Rate (SPS) | 8, 16, 32, 128 | 15, 30, 60, 240 | Different output data rates affect measurement speed and noise trade-off; the ADS1110 offers higher throughput. |
| Supply Voltage Range | 2.7 V to 5.5 V | 2.7 V to 5.5 V | Same supply range means both are compatible with common 3.3 V and 5 V systems. |
| Interface | I2C | I2C | Both use I2C, so bus compatibility and addressing considerations are similar. |
| Package | SOT-23-6 | SOT-23-6 | Identical package enables drop-in PCB footprint compatibility. |
| Internal Reference | Yes (on-chip) | Yes (on-chip) | Both include an internal reference, simplifying design and reducing external component count. |
| Operating Temperature Range | -40 °C to +85 °C | -40 °C to +85 °C | Same temperature range supports use in similar industrial and commercial environments. |

Frequently asked questions
What are the key differences between the ADS1100A0IDBVR and ADS1110A6IDBVR?
The ADS1100A0IDBVR is a 16-bit delta-sigma ADC with a fixed gain of 1 and a programmable data rate of 8, 16, 32, or 128 SPS, while the ADS1110A6IDBVR is a 16-bit delta-sigma ADC with a fixed gain of 8 and a fixed data rate of 15 SPS. Both are single-channel devices in a SOT-23-6 package with an I2C interface, but they differ in PGA gain setting and output data rate configuration.
Are the ADS1100A0IDBVR and ADS1110A6IDBVR pin-compatible?
Yes. Both devices are offered in the same 6-pin SOT-23 (DBV) package and share the same pinout: VDD, GND, SCL, SDA, VIN+, and VIN-. This allows them to be used on the same PCB footprint, but the gain and data rate differences must be evaluated for the target application.
What is the input voltage range for each device?
The ADS1100A0IDBVR has a fixed PGA gain of 1, so its differential input range is ±VDD (with VDD from 2.7 V to 5.5 V). The ADS1110A6IDBVR has a fixed PGA gain of 8, giving a differential input range of ±VDD/8. The absolute input voltage on each pin must remain within the supply rails (GND to VDD) for both devices.
How do the data rates of the ADS1100A0IDBVR and ADS1110A6IDBVR compare?
The ADS1100A0IDBVR supports selectable data rates of 8, 16, 32, and 128 SPS via the I2C configuration register. The ADS1110A6IDBVR has a fixed data rate of 15 SPS. The ADS1100A0IDBVR therefore offers higher maximum throughput, while the ADS1110A6IDBVR provides a single fixed rate suited to low-speed, high-resolution measurements.
Do both devices use the same I2C interface and supply voltage?
Yes. Both the ADS1100A0IDBVR and ADS1110A6IDBVR use a two-wire I2C-compatible serial interface and operate from a single supply of 2.7 V to 5.5 V. Both are 16-bit delta-sigma ADCs with on-chip programmable gain amplifiers, though the gain is factory-fixed differently between the two variants.
Can the ADS1110A6IDBVR replace the ADS1100A0IDBVR in an existing design?
Only after validating the differences. The ADS1110A6IDBVR has a fixed gain of 8 and a fixed 15 SPS rate, whereas the ADS1100A0IDBVR has gain 1 and selectable rates up to 128 SPS. A replacement changes the input range and throughput, so the signal chain, reference scaling, and timing must be re-evaluated against the manufacturer datasheets before substitution.
What resolution and architecture do the ADS1100A0IDBVR and ADS1110A6IDBVR provide?
Both are 16-bit delta-sigma (ΔΣ) analog-to-digital converters with a single differential input channel and an on-chip PGA. The ADS1100A0IDBVR provides 16-bit resolution with gain fixed at 1, and the ADS1110A6IDBVR provides 16-bit resolution with gain fixed at 8. Both integrate the ADC, PGA, and I2C interface in a SOT-23-6 package.
Which device is better suited for low-level signal measurement?
The ADS1110A6IDBVR, with its fixed PGA gain of 8, is intended for smaller differential signals because it amplifies the input by 8 before conversion, improving effective resolution for low-amplitude sensors. The ADS1100A0IDBVR, with gain 1, is suited to larger input signals up to the supply rails. Selection should be based on the sensor output amplitude and required full-scale range per the datasheets.
