ADS1100A7IDBVR

Analog To Digital Converters (ADC) Overview

The ADS1100A7IDBVR 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 onboard programmable gain amplifier (PGA) with gains of 1, 2, 4, or 8. The device operates on a single power supply ranging from 2.7 V to 5.5 V 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 I²C slave address corresponds to the A7 variant (1001111). Confirm the package marking indicates AD7. Ensure the application voltage remains within the 2.7 V to 5.5 V range. Check that the input signal does not exceed the absolute maximum ratings relative to VDD. Validate compatibility with the target I²C bus speed modes.

Analog To Digital Converters (ADC) Selection Notes

Select this variant when a specific I²C address of 1001111 is required to avoid bus conflicts. Choose based on the need for high resolution (16 bits) and low noise (4 µVp-p). Consider the SOT-23-6 package size for space-constrained designs. Evaluate if the internal clock generator meets timing requirements, as external clocks are not supported.

Analog To Digital Converters (ADC) Part Context

The ADS1100A7IDBVR belongs to the ADS1100 family of precision ADCs. Variants are distinguished primarily by their factory-set I²C addresses (A0 through A7). All variants share identical electrical characteristics, pinouts, and functionality. The 'DBVR' suffix denotes the SOT-23-6 surface-mount package and tape-and-reel shipping format.
