Frequently Asked Questions (FAQ)
What are the critical layout considerations when designing a PCB for the ADS124S06IRHBR to ensure 24-bit ADC performance in noisy industrial environments?
To maintain the ADS124S06IRHBR’s 24-bit precision, isolate analog and digital grounds with a single-point connection near the device’s exposed pad, route the reference voltage (REFIN) with a low-impedance guard ring, and place decoupling capacitors (100 nF + 10 µF) as close as possible to the AVDD and DVDD pins. Avoid routing high-speed digital signals (e.g., SPI clocks) near analog input traces, and use a solid ground plane beneath the 32-VQFN package to minimize thermal and electrical noise. Poor layout can introduce microvolt-level errors that degrade effective resolution.
Can the ADS124S06IRHBR safely replace the ADS1256 in a strain gauge measurement system without hardware or firmware changes?
No, direct replacement is not recommended. While both are 24-bit sigma-delta ADCs, the ADS124S06IRHBR operates at a maximum sampling rate of 4 kSPS (vs. 30 kSPS for the ADS1256) and uses an integrated PGA and MUX, requiring different register configurations and timing. Additionally, the ADS1256 has eight differential inputs, whereas the ADS124S06IRHBR supports six single-ended inputs—this may necessitate signal conditioning changes. Firmware must be rewritten to accommodate the SPI protocol differences and internal calibration routines.
How does the internal reference of the ADS124S06IRHBR compare to an external precision reference like the REF5025 in terms of long-term stability and temperature drift?
The ADS124S06IRHBR’s internal reference has a typical drift of 10 ppm/°C and ±0.05% initial accuracy, which may be insufficient for high-precision applications over wide temperature ranges. In contrast, the REF5025 offers 3 ppm/°C drift and ±0.05% initial accuracy with better long-term stability. For applications requiring <10 µV error over time (e.g., medical or metrology), use an external reference like the REF5025 connected to the REFIN pin, and disable the internal reference via register configuration to avoid contention.
What risks should I consider when operating the ADS124S06IRHBR near its -50°C lower temperature limit in outdoor sensor applications?
At -50°C, ensure that all supporting components (e.g., reference voltage, input filters, and decoupling capacitors) remain within their specified operating ranges, as capacitor ESR and reference drift can degrade performance. The ADS124S06IRHBR itself is rated for this temperature, but solder joint reliability on the 32-VQFN package may be compromised under thermal cycling without proper pad design and underfill. Additionally, verify that the input signal source impedance remains low (<1 kΩ) to prevent charge injection errors from the internal PGA, which can become more pronounced at extreme cold due to reduced carrier mobility.
Is it safe to share the SPI bus between the ADS124S06IRHBR and other high-speed digital devices like an STM32 microcontroller without signal integrity issues?
Yes, but only with careful design. The ADS124S06IRHBR supports SPI Mode 1 or 3 with clock rates up to 10 MHz. To avoid crosstalk and ringing, keep SPI traces short, use series termination resistors (22–33 Ω) near the ADC, and ensure the microcontroller’s GPIO slew rate is controlled. Since the ADS124S06IRHBR lacks Schmitt-trigger inputs, noisy environments may require level-shifting or buffering. Also, avoid simultaneous switching of other digital lines during ADC data readout to prevent ground bounce that could corrupt the LSBs of the 24-bit result.
