ADS1115IRUGR

Analog To Digital Converters (ADC) Overview

The Texas Instruments ADS1115IRUGR is a 16-bit Delta-Sigma analog-to-digital converter (ADC) housed in a 10-pin X2-DFN package. It features four input channels with support for two differential or four single-ended inputs. The device operates on a supply voltage range of 2V to 5.5V and supports serial I2C communication interfaces. It achieves a maximum sampling rate of 860 samples per second (SPS). The component includes an integrated programmable gain amplifier (PGA) and a digital comparator, functioning within a temperature range of -40°C to 125°C.

Analog To Digital Converters (ADC) Feature Summary

• Integrates a programmable gain amplifier and input multiplexer to support flexible differential and single-ended measurement configurations.
• Includes an internal low-drift voltage reference and oscillator to minimize external component requirements.
• Features a built-in digital comparator for simplified system monitoring and threshold detection.
• Supports single-shot mode operation to automatically power down between conversions for reduced idle power consumption.

Analog To Digital Converters (ADC) Applications

• Battery monitoring systems
• Industrial process control
• Portable instrumentation
• Medical instrumentation
• Smart transmitters

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific ordering suffix against the manufacturer's current datasheet to confirm package type and tape-and-reel specifications. Ensure compatibility with the target I2C address configuration and supply voltage requirements before finalizing procurement decisions.

Analog To Digital Converters (ADC) Selection Notes

Select this component when high resolution and small form factor are critical constraints. The integrated PGA allows direct connection to low-level sensors without external amplification. Verify that the required sampling rate does not exceed 860 SPS and that the I2C bus speed matches the system design.

Analog To Digital Converters (ADC) Part Context

This part belongs to the ADS111x family of precision ADCs from Texas Instruments. It shares architectural similarities with the ADS1113, ADS1114, and ADS1119 but offers distinct channel counts and performance characteristics. The IRUGR suffix indicates a specific reel packaging variant within the broader product line.

Analog To Digital Converters (ADC) Replacement Considerations

ADS1114: Offers similar 16-bit resolution but with fewer input channels. ADS1119: Provides higher sampling rates up to 860 SPS with different channel configurations. ADS1015: An 12-bit alternative with lower resolution but potentially lower cost.
