ADS112C04IPW

Analog To Digital Converters (ADC) Overview

The ADS112C04IPW is a low-power, 16-bit analog-to-digital converter (ADC) from Texas Instruments, featuring four differential or single-ended input channels. It utilizes a sigma-delta architecture with an integrated programmable gain amplifier (PGA) and supports I2C digital interfaces for system connectivity. The device operates on analog and digital supply voltages ranging from 2.3 V to 5.5 V, consuming only 1.4 mW of power at maximum sampling rates. It offers a data rate up to 2 kSPS and includes internal and external reference options with a nominal voltage of 2.048 V. Designed for precision applications, it provides 50/60 Hz rejection capabilities and features excitation current sources. The component is housed in a TSSOP-16 package and functions reliably within an industrial temperature range of -40°C to +125°C.

Analog To Digital Converters (ADC) Feature Summary

• Integrated excitation current sources (iDACs) facilitate direct sensor interfacing without additional external components.
• Built-in oscillator and temperature sensor reduce system complexity and board space requirements.
• Supports both internal and external reference configurations to accommodate varying precision needs.

Analog To Digital Converters (ADC) Applications

• Industrial process control systems requiring multi-channel signal acquisition
• Portable battery-powered instrumentation due to low power consumption
• Medical equipment utilizing high-resolution data conversion

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific ordering suffix to confirm the package type and tape-and-reel versus tube packaging configuration. Ensure compatibility with the target I2C bus speed and address settings during integration. Confirm that the operating voltage range aligns with the system's power supply rails. Check for moisture sensitivity level requirements if the component has been stored for extended periods prior to assembly.

Analog To Digital Converters (ADC) Selection Notes

Select this model when four independent channels are required within a compact footprint. Consider the ADS112U04IPW variant if UART communication is preferred over I2C. Evaluate the ADS112C04IRTER option if surface-mount reflow soldering with a WQFN package is necessary for the PCB layout constraints.

Analog To Digital Converters (ADC) Part Context

This component belongs to the ADS112C04 series of precision ADCs designed for cost-sensitive, high-performance applications. It shares architectural similarities with other devices in the family but is distinguished by its specific I2C interface and four-channel capability. The IPW suffix denotes the TSSOP-16 plastic package, differentiating it from the IRTER variant which uses a smaller WQFN form factor.

Analog To Digital Converters (ADC) Replacement Considerations

The ADS112U04IPW serves as a functional alternative offering UART interface support instead of I2C. For reduced physical footprint requirements, the ADS112C04IRTER provides identical electrical performance in a 16-WQFN package. Designers must verify pinout compatibility and software register mapping when transitioning between these variants.
