ADS1100A5IDBVR

Analog To Digital Converters (ADC) Overview

The ADS1100A5IDBVR is a self-calibrating, 16-bit delta-sigma analog-to-digital converter (ADC) from Texas Instruments. It features a fully differential input stage and an integrated programmable gain amplifier (PGA) with selectable gains of 1, 2, 4, or 8. The device operates on a single power supply ranging from 2.7V to 5.5V and utilizes an I²C-compatible serial interface for communication. It supports data rates of 8, 16, 32, or 128 samples per second. The component is housed in a compact SOT-23-6 package and includes continuous self-calibration to maintain accuracy without user intervention.

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific I²C address variant required for the design, as the 'A5' suffix denotes a fixed factory-set address distinct from other ADS1100 variants. Confirm that the SOT-23-6 tape and reel packaging aligns with automated assembly requirements. Ensure the selected data rate and PGA setting meet the noise and bandwidth specifications for the target application.

Analog To Digital Converters (ADC) Selection Notes

Select this component when high-resolution differential measurements are needed in space-constrained designs. The internal clock generator simplifies design by removing external oscillator requirements. 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

The ADS1100A5IDBVR belongs to the ADS1100 family of precision ADCs. The 'A5' designation specifically identifies the unit with the I²C address 1001101. Other variants in the series share identical electrical performance but differ only in their pre-programmed slave addresses, allowing multiple devices to be used on a single bus without hardware conflicts.

Analog To Digital Converters (ADC) Replacement Considerations

Other ADS1100 variants (e.g., ADS1100A0IDBVR through ADS1100A7IDBVR) are pin-compatible and functionally identical except for the fixed I²C address. Ensure the replacement part's address does not conflict with existing devices on the I²C bus.
