ADS112U04IRTET

Analog To Digital Converters (ADC) Overview

The ADS112U04IRTET is a low-power, 16-bit analog-to-digital converter (ADC) from Texas Instruments, housed in a 16-pin WQFN package. It features a sigma-delta architecture with four differential or single-ended input channels and supports sampling rates up to 2 kSPS. The device operates on dual power supplies ranging from 2.3 V to 5.5 V for both analog and digital domains. Key electrical specifications include a gain error of 0.015% and a typical power consumption of 1.4 mW. It utilizes a UART interface for data communication and includes an internal oscillator.

Analog To Digital Converters (ADC) Feature Summary

• Integrated programmable gain amplifier (PGA) and excitation current sources (iDACs) for sensor interfacing
• Built-in temperature sensor and GPIO pins for system monitoring and control
• Supports 50 Hz and 60 Hz line-frequency rejection for noise reduction
• Small form factor design suitable for space-constrained applications

Analog To Digital Converters (ADC) Applications

• Industrial process control systems requiring multi-channel signal acquisition
• Portable instrumentation and battery-powered measurement devices
• Medical equipment utilizing bridge sensors or thermocouples
• Weight scales and load cell interfaces

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix 'IRTET' confirms the tape-and-reel packaging format upon ordering. Confirm that the UART interface requirement aligns with the host microcontroller capabilities, as this variant differs from SPI or I2C versions within the same family. Ensure compatibility with the 2.3 V to 5.5 V supply range for both analog and digital rails during system design validation.

Analog To Digital Converters (ADC) Selection Notes

Select this model when a UART interface is preferred over SPI or I2C for the ADS112U04 series. It is appropriate for designs requiring four channels with moderate speed (2 kSPS) and high accuracy (16-bit). Consider alternative packages like IPW if through-hole mounting is required, or other suffixes if SPI/I2C connectivity is necessary instead of UART.

Analog To Digital Converters (ADC) Part Context

This component belongs to the ADS112U04 family of precision ADCs designed for low-power applications. It shares core architectural features with variants such as the ADS112U04IRTER, differing primarily in packaging configuration. The device integrates a mux, PGA, and delta-sigma modulator into a compact solution for high-accuracy data conversion tasks.

Analog To Digital Converters (ADC) Replacement Considerations

ADS112U04IRTER serves as a direct functional substitute with identical electrical characteristics but may differ in reel quantity or specific tape packaging details.
