ADS1110A7IDBVR

Analog To Digital Converters (ADC) Overview

The ADS1110A7IDBVR is a precision, continuous self-calibrating analog-to-digital converter (ADC) from Texas Instruments. It features a 16-bit Sigma-Delta architecture with a single differential or single-ended input channel. The device integrates an internal 2.048 V reference and a programmable gain amplifier (PGA) with gains of 1, 2, 4, or 8. It operates on a single supply voltage ranging from 2.7 V to 5.5 V for both analog and digital domains. Data is transmitted via an I2C-compatible serial interface. The component supports configurable data rates of 15, 30, 60, or 240 samples per second and functions within a temperature range of -40°C to +125°C.

Analog To Digital Converters (ADC) Feature Summary

• Integrates a high-precision internal voltage reference and programmable gain amplifier to support small signal measurements without external components.
• Features a continuous self-calibration mechanism that minimizes offset and gain errors over time and temperature variations.
• Utilizes a standard I2C serial interface for simplified system integration and reduced pin count requirements.

Analog To Digital Converters (ADC) Applications

• Portable instrumentation requiring high resolution in limited space
• Industrial process control systems with I2C connectivity
• Smart transmitters for sensor signal conditioning

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix 'A7' against the official datasheet to confirm the exact I2C address configuration, as this variant differs from other ADS1110 models. Ensure the SOT-23-6 package type matches the PCB footprint design. Confirm RoHS compliance status through the manufacturer's current documentation before finalizing procurement specifications.

Analog To Digital Converters (ADC) Selection Notes

Select this model when a fixed I2C address corresponding to the 'A7' suffix is required for bus addressing purposes. Compare power consumption requirements between continuous conversion mode and single-shot mode. Evaluate if the integrated PGA range covers the expected input signal amplitude to maximize resolution without clipping.

Analog To Digital Converters (ADC) Part Context

This component belongs to the ADS1110 family of ultra-small, low-power ADCs. It shares core architectural similarities with variants like the ADS1110A0IDBVR and ADS1110A4IDBVT, differing primarily in factory-set I2C slave addresses defined by the alphanumeric suffix. All variants maintain identical electrical performance characteristics and pinouts.

Analog To Digital Converters (ADC) Replacement Considerations

ADS1110A0IDBVR: Identical electrical specifications; verify I2C address compatibility. ADS1110A4IDBVT: Pin-compatible alternative; check address mapping. ADS1110A5IDBVT: Similar performance; confirm address settings.
