ADS1100A6IDBVRG4

Analog To Digital Converters (ADC) Overview

The ADS1100A6IDBVRG4 is a precision, continuously self-calibrating 16-bit delta-sigma analog-to-digital converter (ADC) from Texas Instruments. It features a fully differential input stage and an I2C-compatible serial interface within a compact SOT-23-6 package. The device operates on a single power supply ranging from 2.7V to 5.5V and supports programmable data rates of 8, 16, 32, or 128 samples per second. An onboard programmable gain amplifier (PGA) offers gains of 1, 2, 4, or 8, enabling high-resolution measurement of small signals. The part utilizes the power supply as the reference voltage for ratiometric conversions.

Analog To Digital Converters (ADC) Procurement Notes

Verify the ordering suffix 'G4' indicates compliance with RoHS standards and lead-free manufacturing specifications. Confirm the 'A6' designation matches the required I2C slave address (1001110) for the target bus configuration. Ensure the 'DBVR' suffix aligns with the tape and reel packaging quantity requirements for automated assembly processes.

Analog To Digital Converters (ADC) Selection Notes

Select this variant when a specific I2C address (AD6) is required to avoid bus conflicts in multi-device systems. The SOT-23-6 package is suitable for space-constrained designs. Consider the input impedance characteristics, which vary with the PGA setting, when interfacing with high-impedance sensors to ensure measurement accuracy.

Analog To Digital Converters (ADC) Part Context

This component belongs to the ADS1100 family of self-calibrating ADCs. The 'A6' suffix designates the specific I2C address variant (1001110), while 'DBVR' indicates the surface-mount SOT-23-6 package in tape and reel format. The 'G4' suffix denotes environmental compliance. All variants in the series share identical electrical performance and pinouts, differing only in their factory-programmed I2C addresses.

Analog To Digital Converters (ADC) Replacement Considerations

Other ADS1100 variants (ADS1100A0 through ADS1100A7) are electrically compatible but possess different fixed I2C addresses. Substitution requires verification that the new address does not conflict with existing devices on the I2C bus.
