Replacement verdict
Compatible functional replacement candidate
The ADS1100A0IDBVRG4 is a functionally compatible replacement candidate for the ADS1100A1IDBVR, sharing the same I2C interface, 16-bit delta-sigma architecture, SOT-23-6 package, and supply voltage range. The only material distinction is the factory-programmed I2C slave address, which must be accounted for in firmware and bus addressing before substitution.

Frequently asked questions
What are the key differences between the ADS1100A1IDBVR and the ADS1100A0IDBVRG4?
Both devices are 16-bit, self-calibrating, delta-sigma analog-to-digital converters from Texas Instruments in a SOT-23-6 package. The primary difference is the factory-programmed I2C address and the gain configuration. The ADS1100A1IDBVR is set to a gain of 1 with I2C address 1001000, while the ADS1100A0IDBVRG4 is set to a gain of 1 with I2C address 1001001. The "G4" suffix indicates Green/RoHS-compliant molding compound, whereas the base part number may use standard molding compound.
Are the ADS1100A1IDBVR and ADS1100A0IDBVRG4 pin-compatible?
Yes. Both parts share the same SOT-23-6 (DBV) package and identical pinout: VDD, GND, SCL, SDA, and the differential analog inputs VIN+ and VIN-. They are physically interchangeable on a PCB, but the I2C address difference must be accounted for in firmware.
What is the I2C address difference between these two variants?
The ADS1100A1IDBVR uses the 7-bit I2C address 1001000 (0x48), while the ADS1100A0IDBVRG4 uses 1001001 (0x49). This allows both devices to coexist on the same I2C bus without address conflict, but firmware must target the correct address for each variant.
What is the resolution and data rate of the ADS1100 family?
The ADS1100 is a 16-bit delta-sigma ADC with programmable data rates of 8, 16, 32, and 128 samples per second (SPS). Resolution and effective noise performance vary with the selected data rate and gain setting, per the Texas Instruments datasheet.
What supply voltage range do the ADS1100A1IDBVR and ADS1100A0IDBVRG4 support?
Both devices operate from a single supply of 2.7 V to 5.5 V, as specified in the Texas Instruments ADS1100 datasheet. This makes them suitable for both 3.3 V and 5 V systems.
Does the "G4" suffix on the ADS1100A0IDBVRG4 affect electrical performance?
No. The G4 suffix denotes Green (RoHS-compliant, lead-free) molding compound and does not change the electrical specifications. The ADS1100A0IDBVRG4 meets the same datasheet parameters as the non-G4 variant, with the difference limited to environmental compliance of the package materials.
Can the ADS1100A1IDBVR and ADS1100A0IDBVRG4 be used together in the same design?
Yes. Because they have different factory-programmed I2C addresses (0x48 and 0x49), both can share a single I2C bus. This is useful for multi-channel designs where two differential inputs are needed, provided the firmware addresses each device correctly.
What is the input configuration of these ADCs?
Both the ADS1100A1IDBVR and ADS1100A0IDBVRG4 provide a fully differential input with a programmable gain amplifier (PGA) supporting gains of 1, 2, 4, and 8. The A1 and A0 variants differ in factory-set gain/address configuration, so the gain setting must be confirmed against the specific orderable part number in the Texas Instruments datasheet.
