Replacement verdict
Compatible functional replacement candidate
The ADS124S06IPBS and ADS124S06IPBSR are functionally equivalent, sharing the same silicon die, package, and full electrical specification; the only distinction is the tape-and-reel packaging designation of the "R" suffix. Either part number can be used interchangeably in the same design, with the choice driven solely by procurement and assembly-format preferences.

Key electrical and mechanical differences between the two devices
| Parameter | ADS124S06IPBS | ADS124S06IPBSR | Why it matters |
|---|---|---|---|
| Resolution (bits) | 24 | 24 | Both parts provide 24-bit delta-sigma conversion, so measurement resolution and dynamic range are identical. |
| Number of input channels | 6 | 6 | Channel count determines how many sensor inputs can be multiplexed without external switching; identical here. |
| Interface type | SPI | SPI | The digital interface must match the host controller; both use SPI, so firmware and bus wiring are interchangeable. |
| Supply voltage range | 2.7 V to 5.25 V (analog and digital) | 2.7 V to 5.25 V (analog and digital) | Supply compatibility ensures the part can be powered from the same rail in a given design without level shifting. |
| Package / mounting type | 32-TQFP, surface mount | 32-TQFP, surface mount | Package and footprint must match for board-level drop-in substitution; both are the same 32-pin TQFP. |
| Operating temperature range | -40 °C to +125 °C | -40 °C to +125 °C | The temperature rating defines the environments where the part can be used; identical ratings mean equal application range. |
| Integrated PGA gain range | 1 to 128 | 1 to 128 | The programmable gain amplifier range sets the smallest measurable signal; identical gain options preserve sensitivity. |
| Data rate (max) | 4 kSPS | 4 kSPS | Maximum output data rate affects achievable sampling speed and filter design; both support the same throughput. |
| Packaging / order quantity | Tray | Tape and reel | The "R" suffix denotes reel packaging for automated assembly, while the base part ships in trays; this affects manufacturing handling but not electrical function. |

Frequently asked questions
What is the difference between the ADS124S06IPBS and the ADS124S06IPBSR?
The ADS124S06IPBS and ADS124S06IPBSR are the same device: a 24-bit, 6-channel, low-power delta-sigma ADC from Texas Instruments in a 32-pin TQFP (PBS) package. The "R" suffix denotes tape-and-reel packaging for automated assembly, while the non-R part is typically supplied in trays or tubes. Electrical specifications, pinout, and functional behavior are identical.
Are the ADS124S06IPBS and ADS124S06IPBSR electrically and functionally interchangeable?
Yes. Both orderable part numbers share the same die, datasheet specifications, pinout, and package (32-pin TQFP). The only difference is the shipping/packaging format, so they are interchangeable in a design provided the board assembly process accommodates the respective packaging.
What are the key specifications of the ADS124S06?
The ADS124S06 is a 24-bit delta-sigma ADC with 6 single-ended or 3 differential inputs, a programmable gain amplifier, and an integrated low-noise PGA. It supports data rates up to 4 kSPS, operates from an analog supply of 2.7 V to 5.25 V (with a separate digital supply), and includes an internal oscillator, reference, and SPI-compatible interface. It is specified over the -40°C to +125°C temperature range.
Which package do the ADS124S06IPBS and ADS124S06IPBSR use?
Both parts use the PBS package, a 32-pin TQFP (Thin Quad Flat Pack). The "IPBS" suffix in the orderable part number identifies this package and the industrial temperature grade.
Why would a design choose the ADS124S06IPBSR over the ADS124S06IPBS?
The ADS124S06IPBSR is supplied in tape-and-reel, which is preferred for high-volume automated pick-and-place assembly lines. The ADS124S06IPBS (tray/tube) is often used for prototyping, low-volume runs, or manual assembly. Selection depends on the manufacturing process rather than electrical requirements.
Can the ADS124S06IPBS and ADS124S06IPBSR be used in precision sensor measurement applications?
Yes. The ADS124S06 family is designed for precision sensor measurement, including temperature (RTD, thermocouple), pressure, and strain-gauge applications, thanks to its 24-bit resolution, low-noise PGA, and integrated reference. Both orderable variants provide identical analog performance.
Do the ADS124S06IPBS and ADS124S06IPBSR differ in temperature grade or qualification?
No. Both are specified with the "I" industrial temperature grade (-40°C to +125°C) and share the same qualification and datasheet limits. The packaging suffix does not change the temperature grade or reliability qualification.
