ADS124S06BIPBS

Overview

The ADS124S06BIPBS is a precision, 24-bit delta-sigma analog-to-digital converter (ADC) from Texas Instruments. It features six independently selectable analog inputs and operates with 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. The device supports data rates up to 4 kSPS and includes a programmable gain amplifier (PGA) with gains from 1 to 128. It integrates a 2.5-V internal voltage reference, dual matched excitation current sources, and four general-purpose I/Os. The component utilizes a TQFP-32 package and functions within an operating temperature range of –50°C to +125°C.

Feature Summary

• Integrates a low-noise programmable gain amplifier for amplifying small signals from resistive bridges or thermocouples.
• Includes dual matched programmable current sources designed for accurate RTD biasing and sensor excitation.
• Features configurable digital filters providing simultaneous 50-Hz and 60-Hz rejection with low-latency conversion results.

Applications

• Sensor transducers and transmitters for temperature, pressure, strain, and flow measurements
• PLC and DCS analog input modules
• Temperature controllers
• Climate chambers and industrial ovens

Procurement Notes

Verify the specific suffix 'PBS' corresponds to the TQFP-32 package variant when sourcing. Confirm that the ordering part number matches the exact resolution and channel count required for the design. Ensure compatibility with the specified analog and digital supply voltage ranges during procurement planning.

Selection Notes

Select this component for applications requiring high-resolution measurement of small-signal sensors with integrated signal conditioning. The choice depends on the need for a 24-bit resolution with six channels and the requirement for onboard PGA and reference circuitry. Consider the TQFP-32 package constraints and the extended industrial temperature range suitability for the target environment.

Part Context

This device belongs to the ADS124S0x family of low-power, low-noise ADCs. It shares architectural similarities with the ADS124S08 but provides six analog inputs instead of twelve. It is distinct from the ADS114S06, which offers 16-bit resolution. The BIPBS suffix indicates the specific package type and commercial grade availability within the broader product line.

Replacement Considerations

ADS124S08IPBS: Offers identical specifications but with 12 analog inputs instead of 6.
