ADS1114IDGSR

Analog To Digital Converters (ADC) Overview

The ADS1114IDGSR is a precision, low-power, 16-bit analog-to-digital converter (ADC) from Texas Instruments. It features an on-chip programmable gain amplifier (PGA), internal voltage reference, and oscillator. The device supports I2C serial interface with configurable addresses. It offers selectable data rates up to 860 samples per second (SPS). Input configurations include one differential channel or two single-ended channels. Operating voltage ranges from 2V to 5.5V. It includes an integrated comparator for threshold monitoring. The package is a 10-pin VSSOP.

Analog To Digital Converters (ADC) Feature Summary

• Integrated 16-bit delta-sigma ADC architecture with built-in PGA and reference
• Configurable I2C interface allowing multiple devices on a single bus
• On-chip programmable comparator for system-level alarm functions
• Low power consumption with automatic shutdown between conversions

Analog To Digital Converters (ADC) Applications

• Portable instrumentation and battery-powered devices
• Industrial process control and sensor signal conditioning
• Smart transmitters and building automation systems

Analog To Digital Converters (ADC) Procurement Notes

Verify the suffix IDGSR corresponds to the 10-VSSOP package and tape-and-reel shipping format. Confirm the operating temperature range matches the industrial specification (-40°C to +125°C). Ensure the I2C address pins are configured correctly for the target application bus topology. Check RoHS compliance status as required by regional regulations.

Analog To Digital Converters (ADC) Selection Notes

Select this component when a single differential input or two single-ended inputs are sufficient. Choose over ADS1115 if four input channels are not required. Consider ADS1112 if only two differential channels are needed at lower speeds. Verify that the I2C interface compatibility meets the microcontroller requirements. Ensure the 860 SPS maximum rate satisfies the signal bandwidth needs.

Analog To Digital Converters (ADC) Part Context

This part belongs to the ADS111x family of 16-bit ADCs. It shares architectural similarities with ADS1113, ADS1114, and ADS1115. The primary distinction lies in the number of available input channels. The IDGSR suffix indicates the specific package type and reel packaging. It is designed for high-accuracy measurements in space-constrained applications.

Analog To Digital Converters (ADC) Replacement Considerations

• ADS1114IDGST: Same electrical specifications but in a different VSSOP-10 package variant.
