ADS1203IRGTR

Overview

The ADS1203IRGTR is a 16-bit, high-precision analog-to-digital converter (ADC) manufactured by Texas Instruments. It utilizes a sigma-delta modulation architecture with an integrated oscillator and supports data rates up to 40 kSPS. The device operates on a single 5 V supply and features a serial interface for digital communication. Housed in a compact 16-VQFN package measuring 3x3 mm, it is designed for applications requiring high accuracy in small form factors. The component functions as a current shunt monitor or general-purpose precision ADC.

Feature Summary

• 16-bit resolution with 40 kSPS maximum sampling rate
• Integrated internal oscillator eliminates external clock requirements
• Single 5V power supply operation simplifies system design
• Compact 16-VQFN (3x3 mm) surface-mount package

Applications

• Current shunt monitoring in industrial systems
• Precision measurement instrumentation
• Medical equipment signal acquisition
• High-resolution sensor interfaces

Procurement Notes

Verify the specific suffix IRGTR corresponds to the 16-VQFN package and industrial temperature range (-40°C to 125°C). Confirm RoHS compliance status and moisture sensitivity level (MSL 2) during storage handling. Ensure ordering documentation matches the manufacturer part number ADS1203IRGTR exactly to avoid variant mismatches.

Selection Notes

Select this component when a 16-bit resolution and 40 kSPS speed are required within a 3x3 mm footprint. It is suitable for designs needing an integrated oscillator to reduce bill of materials. Compare against the IPWT TSSOP-8 variant if through-hole or larger package space is available. Verify that the single 5V supply constraint aligns with the system power architecture.

Part Context

This part belongs to the ADS1203 family of low-power, 16-bit sigma-delta ADCs from Texas Instruments. The IRGTR suffix denotes the tape-and-reel packaging format intended for automated surface-mount assembly. It shares core specifications with other ADS1203 variants but differs in package type and thermal rating.

Replacement Considerations

The ADS1203IPWT serves as a pin-compatible alternative in a TSSOP-8 package. Other ADS1203 variants may offer different packaging options while maintaining identical electrical performance. Verify pinout compatibility before substitution.
