ADS1118IRUGT

Analog To Digital Converters (ADC) Overview

The ADS1118IRUGT is a precision, low-power, 16-bit analog-to-digital converter (ADC) from Texas Instruments. It utilizes a delta-sigma architecture and operates on a single supply voltage ranging from 2V to 5.5V. The device features an integrated multiplexer supporting two differential or four single-ended inputs, a programmable gain amplifier (PGA), an internal voltage reference, and an oscillator. It includes a high-precision temperature sensor for system monitoring or cold-junction compensation. Data is transmitted via a standard SPI interface. The component is rated for operation between -40°C and +125°C and is housed in a 10-X2QFN package.

Analog To Digital Converters (ADC) Feature Summary

• Integrates a 16-bit delta-sigma ADC with a multiplexer, PGA, and internal reference in an ultra-small footprint.
• Includes a high-precision temperature sensor suitable for system-level monitoring or thermocouple cold-junction compensation.
• Supports flexible input configurations through a multiplexer that handles both differential and single-ended signals.
• Operates efficiently in power-constrained environments with automatic shutdown capabilities in single-shot mode.

Analog To Digital Converters (ADC) Applications

• Battery-powered portable instrumentation
• Industrial process control systems
• Thermocouple measurement interfaces
• Strain gauge and load cell signal conditioning

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix IRUGT corresponds to the industrial temperature grade (-40°C to +125°C) and the X2QFN-10 package configuration. Confirm RoHS compliance status and moisture sensitivity level requirements during storage and handling. Ensure the ordering information matches the exact pinout and electrical specifications required for the target design.

Analog To Digital Converters (ADC) Selection Notes

Select this component when space constraints are critical due to its industry-leading small package size. Choose this model over I2C-based alternatives if a serial peripheral interface is preferred for higher data throughput or simpler microcontroller integration. Consider the internal temperature sensor if external sensing components need to be minimized.

Analog To Digital Converters (ADC) Part Context

This part belongs to the ADS111x family of ultra-small precision ADCs. It shares architectural similarities with the ADS1018 but offers higher resolution at 16 bits compared to the 12-bit ADS1018. Unlike the ADS1115, which uses an I2C interface, this variant employs an SPI interface for data communication, providing flexibility in system bus design.

Analog To Digital Converters (ADC) Replacement Considerations

ADS1118IDGST: Pin-compatible alternative in VSSOP-10 packaging with identical electrical characteristics. ADS1018IRUGT: Lower resolution (12-bit) option within the same package and interface configuration.
