Replacement verdict
Compatible functional replacement candidate
The ADS1110A1IDBVR and ADS1100A5IDBVR share the same I2C interface, SOT-23-6 package, and 16-bit delta-sigma architecture, making the ADS1100A5IDBVR a viable functional substitute in many designs. However, the differing programmable gain amplifier settings and full-scale input ranges require careful validation against the target application's signal chain before final adoption.

Key electrical and mechanical differences between the two devices
| Parameter | ADS1110A1IDBVR | ADS1100A5IDBVR | Why it matters |
|---|---|---|---|
| Resolution (bits) | 16 | 16 | Both are 16-bit delta-sigma ADCs, so resolution is equivalent for precision measurement applications. |
| Programmable Gain Amplifier (PGA) settings | 1, 2, 4, 8 | 1, 2, 4, 8 | Identical gain options allow the same small-signal amplification range for both parts. |
| Data rate (SPS) | 15, 30, 60, 240 | 8, 16, 32, 128 | Different output data rates affect measurement speed and noise performance; the ADS1110 offers faster maximum throughput. |
| Supply voltage range (V) | 2.7 to 5.5 | 2.7 to 5.5 | Both operate over the same supply range, allowing use in identical power domains. |
| Interface | I2C | I2C | Both use I2C, so the same bus and firmware protocol can be reused. |
| Input type | Differential | Differential | Differential inputs on both parts provide common-mode noise rejection for sensor interfaces. |
| Internal reference | Yes (on-chip) | Yes (on-chip) | On-chip references simplify design and reduce external component count for both devices. |

Frequently asked questions
What are the key differences between the ADS1110A1IDBVR and ADS1100A5IDBVR?
Both are 16-bit delta-sigma ADCs from Texas Instruments in a SOT-23-6 package with I2C interface. The ADS1110A1IDBVR has a programmable gain amplifier (PGA) with gains of 1, 2, 4, and 8, and supports data rates of 15, 30, 60, and 240 SPS. The ADS1100A5IDBVR has a fixed gain of 1 and supports data rates of 8, 16, 32, and 128 SPS. The ADS1110A1IDBVR offers higher throughput and selectable gain, while the ADS1100A5IDBVR provides lower-speed conversion with fixed unity gain.
Are the ADS1110A1IDBVR and ADS1100A5IDBVR pin-compatible?
Yes. Both devices are offered in the same 6-pin SOT-23 (DBV) package with the same pin functions: VDD, GND, SCL, SDA, and the analog input pins. This allows a common PCB footprint, but electrical differences such as gain and data rate must be validated before substitution.
What is the resolution and architecture of these two ADCs?
Both the ADS1110A1IDBVR and ADS1100A5IDBVR are 16-bit delta-sigma analog-to-digital converters with a differential input and an on-chip oscillator. They provide 16-bit resolution over the I2C interface.
How do the gain settings differ between the ADS1110A1IDBVR and ADS1100A5IDBVR?
The ADS1110A1IDBVR includes a programmable gain amplifier selectable for gains of 1, 2, 4, and 8. The ADS1100A5IDBVR has a fixed gain of 1. Designs requiring input signal amplification should account for this difference.
What data rates are supported by each device?
The ADS1110A1IDBVR supports output data rates of 15, 30, 60, and 240 samples per second. The ADS1100A5IDBVR supports 8, 16, 32, and 128 samples per second. The ADS1110A1IDBVR provides higher maximum throughput.
What supply voltage and interface do these ADCs require?
Both devices operate from a single supply in the 2.7 V to 5.5 V range and communicate over a two-wire I2C-compatible serial interface. They are suited to low-power, space-constrained sensor and measurement applications.
Can the ADS1100A5IDBVR be used as a drop-in replacement for the ADS1110A1IDBVR?
Not as a direct drop-in replacement without design review. Although the package and pinout are the same, the ADS1100A5IDBVR has fixed gain of 1 and lower data rates (8 to 128 SPS) compared with the ADS1110A1IDBVR's selectable gains and 15 to 240 SPS rates. Firmware configuration and signal-chain requirements must be revalidated.
