Replacement verdict
Compatible functional replacement candidate
The ADS1100A0IDBVR and ADS1100A1IDBVR 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 A1 variant can serve as a direct replacement for the A0 variant provided the system firmware is updated to the corresponding address.

Frequently asked questions
What is the main difference between the ADS1100A0IDBVR and ADS1100A1IDBVR?
The primary difference is the factory-programmed I2C slave address. The ADS1100A0IDBVR uses I2C address 1001000, while the ADS1100A1IDBVR uses I2C address 1001001. Both are otherwise identical 16-bit, self-calibrating, delta-sigma analog-to-digital converters in a SOT-23-6 package.
Are the ADS1100A0IDBVR and ADS1100A1IDBVR pin-compatible?
Yes. Both devices are offered in the same SOT-23-6 (DBV) package with identical pin functions: VDD, GND, VIN+ (A0), VIN- (A1), SDA, and SCL. The PCB land pattern and pinout are the same; only the I2C address differs.
Can the ADS1100A0IDBVR and ADS1100A1IDBVR be used on the same I2C bus?
Yes. Because they have different fixed I2C slave addresses (1001000 vs 1001001), both devices can coexist on the same I2C bus without address conflict, provided bus capacitance and pull-up requirements are satisfied.
What is the resolution and data rate of these ADCs?
Both the ADS1100A0IDBVR and ADS1100A1IDBVR are 16-bit delta-sigma ADCs. The data rate is programmable via the configuration register to 8 SPS, 16 SPS, 32 SPS, or 128 SPS. Resolution in effective bits depends on the selected data rate and gain setting, per the manufacturer datasheet.
What supply voltage and interface do these devices support?
Both devices operate from a single supply of 2.7 V to 5.5 V and communicate over an I2C-compatible serial interface supporting standard and fast modes. They include an on-chip programmable gain amplifier with gain settings of 1, 2, 4, and 8.
Are the ADS1100A0IDBVR and ADS1100A1IDBVR drop-in replacements for each other?
They are electrically and mechanically interchangeable in most designs, but firmware must be updated to use the correct I2C address. The A0 variant responds at 1001000 and the A1 variant at 1001001; using the wrong address will prevent communication.
What is the operating temperature range for these components?
Both the ADS1100A0IDBVR and ADS1100A1IDBVR are specified for operation over the industrial temperature range of -40°C to +85°C, as stated in the manufacturer datasheet.
