ADS1100A3IDBVTG4

Analog To Digital Converters (ADC) Overview

The Texas Instruments ADS1100A3IDBVTG4 is a single-channel, 16-bit delta-sigma analog-to-digital converter (ADC) housed in a compact SOT-23-6 surface-mount package. It operates on a supply voltage range of 2.7 V to 5.5 V and supports both differential and single-ended input configurations. The device features an integrated programmable gain amplifier (PGA), an internal oscillator, and self-calibration capabilities. Communication is handled via a standard I2C serial interface with selectable addresses. It delivers a maximum sampling rate of 128 samples per second and functions reliably within an industrial temperature range of -40°C to +85°C.

Analog To Digital Converters (ADC) Feature Summary

• Integrates a 16-bit delta-sigma ADC with a built-in programmable gain amplifier for flexible signal conditioning.
• Features self-calibrating architecture that eliminates the need for external precision reference components.
• Supports dual-mode input acceptance for both differential and single-ended sensor connections.
• Utilizes a simple two-wire I2C digital interface with configurable address options.

Analog To Digital Converters (ADC) Applications

• Battery-powered portable instrumentation systems
• Industrial process control loop monitoring
• Precision weight scale and load cell measurement

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix 'G4' indicates lead-free compliance and RoHS status when sourcing. Confirm the exact factory packaging type, such as tape and reel or cut tape, matches your assembly requirements. Ensure the selected variant aligns with the required PGA gain setting and I2C address configuration for your circuit design.

Analog To Digital Converters (ADC) Selection Notes

Select this component when high resolution is required in a minimal footprint application. Compare against other ADS1100 variants to identify the correct PGA gain factor and I2C address code. Verify that the 128 S/s data rate meets the system's bandwidth needs and that the 2.7 V minimum supply voltage is compatible with the target power source.

Analog To Digital Converters (ADC) Part Context

This part belongs to the ADS1100 family of low-power, high-precision analog-to-digital converters from Texas Instruments. The family shares common architectural features including sigma-delta modulation and I2C connectivity. Variations within the series typically differ by PGA gain settings, I2C address codes, and manufacturing compliance suffixes.

Analog To Digital Converters (ADC) Replacement Considerations

Direct substitutes include other ADS1100 variants with different gain or address codes, such as ADS1100A0IDBVT or ADS1100A1IDBVT. Cross-family replacements like the ADS1110 offer higher speed but may require software adjustments due to different register maps.
