ADS1100A3IDBVR

Analog To Digital Converters (ADC) Overview

The Texas Instruments ADS1100A3IDBVR is a 16-bit delta-sigma analog-to-digital converter (ADC) housed in a compact SOT-23-6 package. It features a single differential or single-ended input channel with an integrated programmable gain amplifier (PGA). The device operates on a supply voltage ranging from 2.7V to 5.5V and supports serial I2C-compatible interfaces. Key electrical specifications include a maximum sampling rate of 128 samples per second, an internal reference, and low power consumption of approximately 270µW at 3V. It functions within a temperature range of -40°C to +85°C.

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix 'A3' against the official datasheet to confirm the exact PGA gain setting, as this variant determines the full-scale input range. Ensure the ordering part number matches the required gain configuration for your application design. Cross-reference the manufacturer's latest documentation to confirm pinout compatibility and any potential updates to the ADS1100 family specifications before finalizing procurement.

Analog To Digital Converters (ADC) Selection Notes

Select the ADS1100A3IDBVR when a fixed PGA gain setting is sufficient for the target signal amplitude, avoiding the need for external gain adjustment circuitry. This model is suitable for designs requiring a small footprint due to the SOT-23-6 packaging. Compare the fixed gain option against other ADS1100 variants if variable gain flexibility is required for different sensor types within the same product line.

Analog To Digital Converters (ADC) Part Context

The ADS1100A3IDBVR belongs to the ADS1100 series of low-power, high-resolution ADCs from Texas Instruments. This series is designed to replace traditional multi-component solutions by integrating the ADC, PGA, and reference into a single chip. The A3 designation typically indicates a specific factory-set gain value, distinguishing it from other variants that may offer different fixed gains or programmable settings.

Analog To Digital Converters (ADC) Replacement Considerations

Direct replacements include other ADS1100 variants such as ADS1100A0IDBVR or ADS1100A1IDBVR, provided the gain requirements are met. The ADS1110 series offers similar functionality but includes an internal oscillator and higher sampling rates. Verify that the substitute component maintains the same SOT-23-6 package and I2C address configuration to ensure board-level compatibility.
