ADS124S08IPBS

Overview

The ADS124S08IPBS is a precision, low-power, 24-bit delta-sigma analog-to-digital converter (ADC) manufactured by Texas Instruments. It features 12 single-ended inputs and supports data rates up to 4 kSPS. The device integrates a programmable gain amplifier (PGA) with gains ranging from 1 to 128, an internal reference voltage source, and a digital filter. It operates on a single supply voltage of 2.7 V to 5.25 V for analog power and 2.7 V to 3.6 V for digital power. The component utilizes a serial peripheral interface (SPI) for communication and is housed in a 32-pin VQFN package.

Feature Summary

• Integrates a 24-bit delta-sigma ADC core with a 12-channel multiplexer and programmable gain amplifier for high-resolution signal conditioning.
• Includes an internal low-drift reference voltage source and digital filter to reduce external component count and system noise.
• Supports flexible input configurations including single-ended and differential modes via SPI interface.

Applications

• High-precision industrial process control systems requiring multi-channel sensor monitoring.
• Weigh scales and load cell measurement applications utilizing bridge sensors.
• Medical instrumentation devices demanding accurate physiological signal acquisition.
• Strain gauge and pressure transducer interfaces in automated testing equipment.

Procurement Notes

Verify the specific suffix IPBS confirms the 32-pin VQFN package and tape-and-reel or tray availability as per the distributor's current listing. Confirm the operating temperature range matches the industrial specification requirements for the target environment. Ensure the order quantity aligns with the manufacturer's standard packaging units to avoid partial reel surcharges or minimum order constraints.

Selection Notes

Select this component when designing systems that require high resolution across multiple channels without external amplifiers. The integrated PGA simplifies front-end design for low-level signals. Consider the 4 kSPS maximum data rate against application bandwidth needs. Verify compatibility with the host microcontroller's SPI speed and voltage levels before integration into the schematic.

Part Context

This part belongs to the ADS124S family of precision ADCs, which also includes the ADS124S06 variant with six channels. The series is designed to replace discrete solutions involving separate amplifiers and references, offering a compact alternative for cost-sensitive, high-performance measurement applications in industrial and scientific markets.

Replacement Considerations

The ADS124S06 serves as a direct pin-compatible alternative within the same family, offering identical performance characteristics but with only six available input channels instead of twelve. Designers requiring fewer channels may consider this option for potential board space reduction.
