ADS1110A3IDBVR

Analog To Digital Converters (ADC) Overview

The ADS1110A3IDBVR is a precision, continuous self-calibrating analog-to-digital converter (ADC) from Texas Instruments. It features a 16-bit resolution and supports sampling rates of 15, 30, 60, or 240 samples per second. The device integrates a programmable gain amplifier (PGA), an internal oscillator, and a voltage reference within a compact SOT-23-6 package. It operates on a single power supply ranging from 2.7 V to 5.5 V and utilizes an I2C-compatible serial interface for communication. The internal 2.048 V reference provides a differential input range of ±2.048 V.

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix 'A3' configuration against the manufacturer datasheet to confirm the fixed address setting associated with this variant. Ensure the SOT-23-6 package marking matches official Texas Instruments specifications. Confirm RoHS compliance status through the latest product information sheet before procurement.

Analog To Digital Converters (ADC) Selection Notes

Select the ADS1110A3IDBVR when space constraints require a small SOT-23-6 footprint alongside high-resolution measurements. This model is suitable for applications requiring low power consumption in single-conversion mode. Verify that the required I2C address aligns with the system bus configuration, as the 'A3' suffix typically denotes a specific hardware address setting.

Analog To Digital Converters (ADC) Part Context

This component belongs to the ADS1110 family of delta-sigma ADCs. It shares core architectural features with variants like the ADS1110A0IDBVR and ADS1110A4IDBVT, differing primarily in factory-programmed I2C address settings defined by the middle letter in the part number. All variants maintain identical electrical performance and pinout configurations.

Analog To Digital Converters (ADC) Replacement Considerations

Direct replacements include other ADS1110 variants such as ADS1110A0IDBVR or ADS1110A4IDBVR, provided the I2C address conflict is resolved via software or bus configuration adjustments. The ADS1100 series offers similar functionality but lacks the internal voltage reference.
