ADS1224IPWTG4

Overview

The ADS1224IPWTG4 is a low-power, 24-bit analog-to-digital converter (ADC) from Texas Instruments. It features four differential or single-ended input channels and utilizes a sigma-delta architecture. The device supports an SPI interface and offers programmable data rates up to 240 samples per second. It operates on a single supply voltage ranging from 2.7 V to 5.5 V for both analog and digital domains. Integrated features include a temperature sensor and rejection capabilities for 50 Hz and 60 Hz power line frequencies. The component is housed in a TSSOP-20 package and is designed for applications requiring high precision and low power consumption.

Feature Summary

• Integrates four input channels with support for both differential and single-ended configurations within a compact form factor.
• Includes an internal temperature sensor and provides inherent rejection of 50 Hz and 60 Hz interference signals.
• Operates efficiently on a single low-voltage supply, supporting data rates up to 240 SPS via a standard serial peripheral interface.

Applications

• Battery-powered portable instrumentation
• Industrial process control systems
• Weight scales and load cell measurements

Procurement Notes

Verify the specific suffix 'G4' indicates compliance with RoHS directives and lead-free manufacturing standards as defined by Texas Instruments. Confirm that the TSSOP-20 package matches the design footprint requirements. Ensure the operating voltage range aligns with the system's power supply rails before integration into the final hardware design.

Selection Notes

Select this component when four independent measurement channels are required alongside high resolution. Consider the trade-off between the maximum 240 SPS data rate and the ultra-low power consumption profile. Verify that the external reference voltage capability meets the accuracy requirements of the target application compared to using an internal reference if available in other variants.

Part Context

This part belongs to the ADS1224 family of precision ADCs. It shares architectural similarities with the ADS1220 and ADS1221 but distinguishes itself through the inclusion of four input channels rather than two. The IPW suffix denotes the TSSOP-20 surface-mount package, while the G4 suffix typically signifies Green/RoHS-compliant manufacturing processes.

Replacement Considerations

The ADS1224IPWR serves as a tape-and-reel alternative to the cut-tape IPWT variant. For applications requiring fewer channels, the ADS1220IPWT or ADS1221IPWT may be suitable substitutes. Cross-reference the ADS1224IPWRG4 for identical electrical specifications with different packaging options.
