ADS1114LIDGSR

Analog To Digital Converters (ADC) Overview

The ADS1114LIDGSR is a precision, low-power, 16-bit analog-to-digital converter (ADC) from Texas Instruments. It features a delta-sigma architecture with an integrated programmable gain amplifier (PGA), internal voltage reference, and oscillator. The device supports I2C communication with four pin-selectable addresses and is compatible with 1.8-V bus voltages. It offers a maximum sampling rate of 860 SPS and operates on a supply voltage range of 2.0 V to 3.6 V. The component consumes 150 μA in continuous-conversion mode and includes a digital comparator with an ALERT output. It is housed in a 10-pin VSSOP package.

Analog To Digital Converters (ADC) Feature Summary

• Integrates a 16-bit delta-sigma ADC core with a programmable gain amplifier for precise signal conditioning.
• Features an internal low-drift voltage reference and a 1-MHz oscillator, eliminating the need for external clocking or references.
• Includes a digital comparator with an open-drain ALERT/RDY output pin for under- and overvoltage detection.
• Supports I2C interface with four pin-selectable addresses and compatibility with 1.8-V logic levels.

Analog To Digital Converters (ADC) Applications

• Supply-voltage monitoring
• Current measurement
• Temperature measurement

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific ordering suffix IDGSR corresponds to the VSSOP-10 package and tape-and-reel delivery format as defined in the manufacturer's orderable information. Confirm that the device meets the required RoHS compliance standards for your assembly process. Ensure the I2C pull-up resistors are selected appropriately for the operating voltage and bus capacitance to maintain timing requirements.

Analog To Digital Converters (ADC) Selection Notes

Select this component when a single differential or single-ended input channel is required alongside high resolution and low power consumption. The ADS1114L is suitable for space-constrained designs due to its ultra-small package size. Consider the ADS1115L if multiple input channels are needed, as it includes an internal multiplexer. Ensure the application voltage does not exceed the absolute maximum ratings to prevent damage.

Analog To Digital Converters (ADC) Part Context

The ADS1114LIDGSR belongs to the ADS111xL family of ultra-small, low-power ADCs. This series is designed for sensor measurement applications where power and space are limited. The 'L' designation indicates support for 1.8-V I2C bus voltages, distinguishing it from standard variants that may require higher logic levels. The device shares architectural similarities with the ADS1014L but offers higher resolution.

Analog To Digital Converters (ADC) Replacement Considerations

The ADS1115LIDGSR serves as a direct functional substitute if additional input channels are required, as it shares the same package and electrical characteristics but includes an internal multiplexer. Other ADS111xL variants may be considered if different package types or data rates are acceptable, provided the I2C interface and voltage ranges remain compatible.
