ADS1100A7IDBVRG4

Analog To Digital Converters (ADC) Overview

The ADS1100A7IDBVRG4 is a precision, continuously self-calibrating 16-bit delta-sigma analog-to-digital converter (ADC) manufactured by Texas Instruments. It features a small SOT-23-6 package and operates from a single power supply ranging from 2.7V to 5.5V. The device utilizes an I²C-compatible serial interface and offers programmable data rates of 8, 16, 32, or 128 samples per second. An onboard Programmable Gain Amplifier (PGA) provides gains of 1, 2, 4, or 8, enabling high-resolution measurement of small signals. The part includes an internal system clock and consumes low current, with typical active mode consumption of 90 µA.

Analog To Digital Converters (ADC) Procurement Notes

Verify the 'G4' suffix against official documentation to confirm environmental compliance status, as standard datasheets may not explicitly detail suffix variations. Confirm the specific I²C address associated with the 'A7' designation prior to integration. Ensure the SOT-23-6 package dimensions match the target PCB footprint requirements.

Analog To Digital Converters (ADC) Selection Notes

Select this component when space-constrained designs require high-resolution differential input conversion. The A7 suffix designates a specific I²C slave address (1001111), which must be accounted for in multi-device bus configurations. Choose based on required PGA gain settings and data rate trade-offs between noise performance and speed.

Analog To Digital Converters (ADC) Part Context

This device belongs to the ADS1100 family of self-calibrating ADCs. The 'A7' identifier specifies the factory-programmed I²C address bits (1001111). The 'DBVR' indicates the SOT-23-6 surface-mount package and tape-and-reel shipping format. The 'G4' suffix typically denotes lead-free and RoHS-compliant manufacturing processes.

Analog To Digital Converters (ADC) Replacement Considerations

Other ADS1100 variants (e.g., ADS1100A0IDBVR) are functionally identical but possess different factory-set I²C addresses. Ensure any substitute part matches the required bus address or allows for address configuration if multiple devices share the same I²C lines.
