Replacement verdict
Compatible functional replacement candidate
The ADS1100A0IDBVRG4 is a functionally equivalent variant of the ADS1100A0IDBVR, sharing identical core electrical and package specifications. The G4 suffix denotes a lead-free/RoHS-compliant manufacturing designation rather than a functional change, making the two parts interchangeable in most designs with only minor validation of the ordering suffix requirements.

Key electrical and mechanical differences between the two devices
| Parameter | ADS1100A0IDBVR | ADS1100A0IDBVRG4 | Why it matters |
|---|---|---|---|
| Resolution | 16 bit | 16 bit | Determines the smallest measurable signal change; identical resolution means equivalent measurement precision. |
| Number of Input Channels | 1 (single-ended or differential) | 1 (single-ended or differential) | Defines how many signals can be measured; matching channel configuration ensures functional interchangeability. |
| Interface Type | I2C | I2C | The digital communication protocol must match for the part to work in the same system bus. |
| Supply Voltage Range | 2.7 V to 5.5 V | 2.7 V to 5.5 V | Must be compatible with the system power rail; identical range ensures the same operating conditions apply. |
| Package / Case | SOT-23-6 | SOT-23-6 | Footprint and pinout must match for drop-in PCB replacement. |
| Mounting Type | Surface Mount | Surface Mount | Assembly method must be compatible with the existing board manufacturing process. |
| Operating Temperature Range | -40 °C to +85 °C | -40 °C to +85 °C | Ensures the device operates reliably across the same environmental conditions. |
| Data Rate (Output) | 8 SPS to 128 SPS (programmable) | 8 SPS to 128 SPS (programmable) | Conversion speed affects system throughput and noise performance; matching rates preserve timing behavior. |
| Internal PGA Gain Settings | 1, 2, 4, 8 | 1, 2, 4, 8 | Gain options determine the measurable input signal range; identical settings ensure equivalent signal scaling. |
| RoHS / Lead-Free Status | RoHS compliant, lead-free (Green) | RoHS compliant, lead-free (Green) | Environmental compliance affects regulatory acceptance and solder process compatibility; both meet the same standard. |

Frequently asked questions
What is the difference between ADS1100A0IDBVR and ADS1100A0IDBVRG4?
The ADS1100A0IDBVR and ADS1100A0IDBVRG4 are functionally identical. The "G4" suffix is a Texas Instruments designation indicating the device is manufactured in a Green (RoHS-compliant, lead-free) package. Both are the same ADS1100 16-bit delta-sigma ADC with I2C interface, gain of 1, in a SOT-23-6 package, specified over the -40°C to +85°C temperature range.
Are the ADS1100A0IDBVR and ADS1100A0IDBVRG4 pin-compatible and interchangeable?
Yes. Both parts share the same SOT-23-6 (DBV) package, pinout, and electrical specifications. The only distinction is the G4 green/RoHS designation, so they are interchangeable in PCB layout and function. Designers should confirm RoHS compliance requirements for their specific application.
What are the key specifications of the ADS1100A0IDBVR?
The ADS1100A0IDBVR is a 16-bit, single-channel delta-sigma ADC with an I2C-compatible serial interface. It offers programmable gain of 1, 2, 4, or 8, data rates of 8, 16, 32, or 128 SPS, an internal oscillator, and operates from a single 2.7 V to 5.5 V supply. It is housed in a 6-pin SOT-23 package.
Does the ADS1100A0IDBVRG4 differ in electrical performance from the ADS1100A0IDBVR?
No. The G4 suffix denotes green (RoHS-compliant) molding compound and does not alter the electrical characteristics. Both variants share the same datasheet specifications, including resolution, gain settings, data rate options, supply voltage range, and I2C interface behavior.
What is the difference between the "A0" gain option and other ADS1100 variants?
The "A0" in ADS1100A0IDBVR designates the factory-programmed default gain setting of 1. Other ADS1100 orderable variants may specify different default gain configurations. The gain is also programmable at runtime via the I2C configuration register, so the A0 designation reflects the default power-up state rather than a hardware limitation.
Can the ADS1100A0IDBVRG4 be used as a drop-in replacement for the ADS1100A0IDBVR in existing designs?
Yes, provided the design already accepts RoHS-compliant (green) components. The package footprint, pinout, supply requirements, and I2C interface are identical. No layout or firmware changes are required for substitution.
What supply voltage and current consumption should be expected for these devices?
Both the ADS1100A0IDBVR and ADS1100A0IDBVRG4 operate from a single supply of 2.7 V to 5.5 V. Typical supply current is approximately 90 µA during continuous conversion, with lower consumption achievable using the single-conversion mode and power-down features described in the datasheet.
