ADS1100A3IDBVT

Analog To Digital Converters (ADC) Overview

The ADS1100A3IDBVT is a 16-bit delta-sigma analog-to-digital converter (ADC) from Texas Instruments, 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 parameters include a maximum sampling rate of 128 samples per second and an operating temperature range of -40°C to +125°C. The component includes internal self-calibration capabilities to maintain accuracy without external reference components.

Analog To Digital Converters (ADC) Feature Summary

• Integrated 16-bit delta-sigma architecture with programmable gain amplifier for high-resolution signal conditioning
• Supports both differential and single-ended input configurations via flexible interface options
• Internal self-calibration system eliminates the need for external precision references or trimming

Analog To Digital Converters (ADC) Applications

• Industrial process control systems requiring precise temperature monitoring
• Portable battery-powered instrumentation due to low power consumption
• High-resolution data acquisition modules in harsh environments

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix 'A3' against the official datasheet to confirm the fixed gain setting, as this variant differs from other ADS1100 models. Ensure the ordering part number matches the required package type and temperature grade. Cross-reference with authorized distributors to confirm current availability and authenticity, as counterfeit components may exist in the market.

Analog To Digital Converters (ADC) Selection Notes

Select the ADS1100A3IDBVT when a fixed gain configuration is sufficient for the application, reducing design complexity compared to adjustable gain variants. Consider the 125°C maximum operating temperature for industrial applications where standard commercial grades are insufficient. Verify that the I2C address settings align with the system bus requirements to avoid communication conflicts.

Analog To Digital Converters (ADC) Part Context

The ADS1100 series represents Texas Instruments' solution for low-cost, high-resolution ADCs in small packages. The A3 suffix typically denotes a specific fixed gain setting within the family, distinguishing it from other variants like A0, A1, or A2 which may offer different gain options or calibration features. This component belongs to the broader ADS1xxx family designed for general-purpose precision measurements.

Analog To Digital Converters (ADC) Replacement Considerations

Direct replacements include ADS1100A0IDBVT, ADS1100A1IDBVT, and ADS1100A2IDBVT, provided the gain settings match the circuit requirements. For pin-compatible alternatives with similar specifications, consider the ADS1110 series, though interface or performance differences must be verified.
