ADS1115IDGSR

Analog To Digital Converters (ADC) Overview

The Texas Instruments ADS1115IDGSR is a 16-bit analog-to-digital converter (ADC) utilizing delta-sigma architecture. It features an internal programmable gain amplifier (PGA), a multiplexer, and an I2C interface within a 10-VSSOP package. The device supports a supply voltage range of 2V to 5.5V for both analog and digital domains. It offers configurable sampling rates up to 860 samples per second and provides four single-ended or two differential input channels. The component operates across a temperature range of -40°C to +125°C.

Analog To Digital Converters (ADC) Feature Summary

• Integrates a 16-bit delta-sigma ADC with a programmable gain amplifier and multiplexer to reduce external component count.
• Supports flexible input configurations through four single-ended or two differential channels accessible via an I2C interface.
• Includes an integrated programmable comparator for simplified system monitoring without host processor intervention.

Analog To Digital Converters (ADC) Applications

• Battery monitoring systems
• Industrial process control
• Portable instrumentation

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific ordering suffix IDGSR confirms the VSSOP-10 package and tape-and-reel delivery format. Confirm the device meets AEC-Q100 qualification requirements if automotive application is intended. Ensure the I2C address configuration aligns with the system bus topology before procurement.

Analog To Digital Converters (ADC) Selection Notes

Select this model when 16-bit resolution and high accuracy are required for low-voltage sensor signals. The integrated PGA eliminates the need for external amplifiers in many applications. Verify that the I2C communication speed and available address pins suit the target microcontroller interface constraints.

Analog To Digital Converters (ADC) Part Context

The ADS1115IDGSR belongs to the ADS111x family of precision ADCs from Texas Instruments. This series includes variants with different resolutions and channel counts, such as the ADS1113 and ADS1114. The IDGSR suffix specifically denotes the surface-mount VSSOP package variant designed for compact electronic designs.

Analog To Digital Converters (ADC) Replacement Considerations

ADS1115IDGST: Same functional specifications but in a TSSOP-10 package instead of VSSOP-10. ADS1114: Offers three differential inputs with identical performance characteristics. ADS1113: Provides a single differential input with the same 16-bit resolution and interface.
