ADS1232IPWG4

Overview

The ADS1232IPWG4 is a 24-bit analog-to-digital converter (ADC) utilizing delta-sigma architecture, manufactured by Texas Instruments. It features two differential inputs configurable for single-ended applications and includes an integrated programmable gain amplifier (PGA). The device operates on dual power supplies ranging from 2.7V to 5.3V for both analog and digital domains. It supports data rates up to 80 samples per second and communicates via an SPI-compatible serial interface. Housed in a 24-pin TSSOP package, it functions within a temperature range of -40°C to +105°C.

Feature Summary

• Integrates a low-noise delta-sigma modulator with a programmable gain amplifier for high-resolution signal conditioning
• Includes internal oscillator and calibration capabilities to minimize external component requirements
• Supports simultaneous 50Hz and 60Hz line-frequency rejection for noise reduction in industrial environments

Applications

• High-precision electronic weighing scales and load cell measurements
• Industrial process control pressure sensors
• Medical instrumentation requiring accurate temperature or pressure detection

Procurement Notes

Verify the G4 suffix indicates lead-free construction and RoHS compliance. Confirm the IPW package designation corresponds to the 24-TSSOP form factor. Ensure the operating voltage range matches system requirements of 2.7V to 5.3V. Check datasheet revisions for any pinout or electrical characteristic updates prior to final design approval.

Selection Notes

Select this component when 24-bit resolution and low noise performance are critical for small signal amplification. The integrated PGA reduces the need for external amplifier stages. Consider the 24-TSSOP package constraints for PCB layout. Verify that the SPI interface timing meets the microcontroller's clock speed requirements for the selected data rate.

Part Context

This part belongs to the ADS123x family of precision ADCs designed for bridge sensor applications. It shares architectural similarities with the ADS1234 but offers two input channels instead of four. The G4 suffix denotes environmental compliance and lead-free manufacturing processes consistent with Texas Instruments' green product standards.

Replacement Considerations

ADS1232IPW serves as the non-G4 equivalent. ADS1234 variants offer four channels. ADS1235 provides additional excitation current sources. ADS1220 offers lower resolution at reduced cost.
