ADS124S06IRHBR

Overview

The ADS124S06IRHBR is a 24-bit, 4-kSPS delta-sigma analog-to-digital converter (ADC) from Texas Instruments. It features six differential or single-ended input channels and integrates a programmable gain amplifier (PGA), internal reference, and excitation current sources (iDACs). The device operates on an analog supply of 2.7 V to 5.25 V and a digital supply of 2.7 V to 3.6 V. It utilizes an SPI interface for data communication and is housed in a 32-pin VQFN package. Key specifications include 50/60 Hz rejection capabilities, an integrated oscillator, a temperature sensor, and GPIO pins. The power dissipation is rated at 1.75 mW.

Feature Summary

• Integrates a 24-bit delta-sigma ADC with a multiplexer and programmable gain amplifier for high-precision signal conditioning.
• Includes built-in excitation current sources suitable for driving bridge sensors such as strain gauges and RTDs.
• Features hardware-configurable 50 Hz and 60 Hz notch filters to reject power line interference.

Applications

• Industrial process control systems requiring multi-channel precision measurement
• Weigh scales and load cell interfaces utilizing bridge sensors
• Thermocouple and resistance temperature detector (RTD) monitoring

Procurement Notes

Verify the specific suffix against official documentation to confirm package type and tape-and-reel configuration. Ensure compatibility with required voltage levels and interface protocols before integration. Check for moisture sensitivity level requirements during storage and handling procedures.

Selection Notes

Select this component when high resolution and multiple input channels are required in a compact form factor. Consider the integrated iDACs if external excitation circuitry needs to be eliminated. Verify that the 4-kSPS data rate meets the system's bandwidth requirements.

Part Context

This part belongs to the ADS124S0x family of low-power, high-precision ADCs. It shares architectural similarities with the ADS124S08 but offers six input channels instead of twelve. It is designed for applications demanding accuracy in noisy industrial environments.

Replacement Considerations

The ADS124S08IRHBR is a compatible alternative within the same family, offering twelve channels instead of six while maintaining similar performance characteristics and pinout compatibility.
