ADS112C04IRTER

Analog To Digital Converters (ADC) Overview

The ADS112C04IRTER is a 16-bit, four-channel analog-to-digital converter (ADC) from Texas Instruments. It utilizes sigma-delta architecture and operates with supply voltages ranging from 2.3 V to 5.5 V for both analog and digital domains. The device supports sampling rates up to 2 kSPS and features an I2C serial interface. Key integrated components include a programmable gain amplifier (PGA), internal oscillator, temperature sensor, and excitation current sources (iDACs). It is housed in a 16-WQFN package with a thermal pad and functions within a temperature range of -40°C to +125°C.

Analog To Digital Converters (ADC) Feature Summary

• Integrated programmable gain amplifier and excitation current sources for direct sensor interfacing
• Built-in temperature sensor and internal oscillator for system monitoring and timing
• Supports differential and single-ended input configurations via multiplexer

Analog To Digital Converters (ADC) Applications

• Industrial process control systems requiring precise signal acquisition
• Portable medical devices utilizing low-power data conversion
• Environmental monitoring sensors needing high-resolution measurements

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix 'TER' indicates reel packaging when sourcing. Confirm the component status as active or obsolete through official Texas Instruments channels prior to design finalization. Ensure compatibility with the required operating voltage range and communication protocol settings during integration planning.

Analog To Digital Converters (ADC) Selection Notes

Select this model for applications requiring four independent channels with 16-bit resolution at moderate speeds. Consider the integrated PGA if signal conditioning amplification is needed upstream. Verify that the I2C interface aligns with the host microcontroller capabilities and that the WQFN package fits the available PCB real estate constraints.

Analog To Digital Converters (ADC) Part Context

This component belongs to the ADS112Cxx series of precision ADCs designed for low-power, small-size applications. It shares architectural similarities with other members like the ADS112C14 but differs in channel count and specific feature sets. The series targets industrial and portable markets where space and power efficiency are critical design parameters.

Analog To Digital Converters (ADC) Replacement Considerations

Direct substitutes within the same family include the ADS112C14IRTER for eight-channel requirements. For UART interface variants, consider the ADS112U04 series. Always verify pinout compatibility and register mapping before swapping between different suffixes or channel counts.
