Replacement verdict
Compatible functional replacement candidate
The ADS1110A1IDBVR and ADS1110A6IDBVR are functionally interchangeable 16-bit delta-sigma ADCs sharing the same SOT-23-6 package, I2C interface, and pinout; the only material distinction is the factory-programmed I2C slave address, so the A6 variant can serve as a drop-in replacement for the A1 variant provided the system firmware is updated to the corresponding address.

Frequently asked questions
What is the main difference between the ADS1110A1IDBVR and the ADS1110A6IDBVR?
The primary difference is the factory-programmed I2C slave address. The ADS1110A1IDBVR is set to address 1001000 (0x48), while the ADS1110A6IDBVR is set to address 1001101 (0x4D). Both are otherwise identical 16-bit delta-sigma ADCs with internal reference, PGA, and oscillator in a SOT-23-6 package.
Are the ADS1110A1IDBVR and ADS1110A6IDBVR functionally identical apart from the I2C address?
Yes. Per the Texas Instruments ADS1110 datasheet, the A1 and A6 variants share the same resolution (16 bits), data rate options (15, 30, 60, 240 SPS), programmable gain amplifier settings (1, 2, 4, 8), internal 2.048 V reference, and on-chip oscillator. The only documented difference is the I2C slave address.
Can the ADS1110A1IDBVR and ADS1110A6IDBVR be used on the same I2C bus simultaneously?
Yes. Because they have different fixed I2C slave addresses (0x48 for A1 and 0x4D for A6), both devices can coexist on the same two-wire bus without address conflict, provided bus capacitance and pull-up sizing are within I2C specification limits.
What is the I2C slave address of each device?
The ADS1110A1IDBVR uses 7-bit slave address 1001000 (0x48). The ADS1110A6IDBVR uses 7-bit slave address 1001101 (0x4D). These addresses are fixed at manufacture and cannot be changed by the user.
Do both variants support the same supply voltage and input range?
Yes. Both operate from a single supply of 2.7 V to 5.5 V and accept differential inputs within the range determined by the selected PGA setting, with the internal 2.048 V reference. Electrical characteristics are identical across the A1 and A6 variants per the TI datasheet.
Are the ADS1110A1IDBVR and ADS1110A6IDBVR pin-compatible and package-compatible?
Yes. Both are offered in the same SOT-23-6 (DBV) package with identical pin functions (VIN+, VIN-, GND, SCL, SDA, VDD). PCB land patterns and footprint are interchangeable; only the I2C address differs.
Which variant should be selected when multiple ADS1110 devices are required on one bus?
Select variants with distinct factory-set addresses. For example, combining an ADS1110A1IDBVR (0x48) with an ADS1110A6IDBVR (0x4D) allows two devices on the same bus. Consult the TI datasheet address table to choose additional variants for more than two devices.
