ADS124S06IPBSR

Overview

The ADS124S06IPBSR is a Texas Instruments 24-bit, 6-channel delta-sigma analog-to-digital converter (ADC) housed in a 32-pin TQFP package. It supports sampling rates up to 4 kSPS with differential or single-ended input configurations. The device operates on an analog supply voltage ranging from 2.7 V to 5.25 V and a digital supply voltage between 2.7 V and 3.6 V. Key electrical parameters include a power dissipation of 1.75 mW and an internal reference voltage of 2.5 V. It functions within a temperature range of -50°C to +125°C and utilizes an SPI interface for data communication.

Feature Summary

• Integrated programmable gain amplifier (PGA) and excitation current sources (iDACs) for sensor signal conditioning
• Built-in 50/60 Hz rejection filters to suppress power line interference
• On-chip temperature sensor and general-purpose I/O (GPIO) pins
• Internal oscillator support for simplified system design

Applications

• Industrial process control systems requiring high-precision multi-channel monitoring
• Weigh scales and load cell measurement applications
• Thermocouple and RTD temperature sensing interfaces
• Strain gauge and pressure transducer signal acquisition

Procurement Notes

Verify the specific suffix IPBSR corresponds to the TQFP-32 package and reel/cut-tape availability. Confirm RoHS compliance status and moisture sensitivity level (MSL) ratings prior to PCB assembly planning. Ensure the ordering part number matches the exact pinout and functional specifications required for the target application design.

Selection Notes

Select this component when a balance of moderate speed (4 kSPS) and high resolution (24-bit) is needed for multiple channels. It is suitable for designs requiring integrated signal conditioning features like iDACs and PGA to reduce external component count. Consider the wide industrial temperature range (-50°C to +125°C) for harsh environment deployments.

Part Context

This device belongs to the ADS124S08 family, which shares similar architectural features but varies in channel count. The ADS124S06 provides six channels, whereas variants like the ADS124S08 offer eight channels. Both utilize the same sigma-delta architecture and are designed for precision measurement tasks in industrial and scientific instrumentation.

Replacement Considerations

The ADS124S08IPBSR is a direct pin-compatible alternative offering additional channels. For lower channel counts, the ADS124S04IPBSR may be considered. Verify that any substitute maintains the same TQFP-32 footprint and compatible supply voltage ranges.
