Professional Insights

Precision measurement design is all about managing error sources. In my experience, thermal EMF in PCB traces can cause microvolt-level errors that limit system accuracy. I always recommend using low-thermal EMF solder and keeping temperature gradients minimal. The CBM92AD16's ±1 LSB INL is excellent, but you need an equally good reference voltage to realize that accuracy. Use the CBMREF16 or a precision external reference. For sensor interfaces, the CBMOPA216's 5µV offset enables direct measurement of small signals. Remember that accuracy is determined by the weakest link in the signal chain.

Key Takeaways

  • Use precision voltage reference
  • Minimize thermal EMF in layout
  • Implement proper shielding
  • Calibrate for best accuracy

Frequently Asked Questions

What accuracy can the solution achieve?

The Precision Measurement Solution achieves excellent accuracy: (1) ADC linearity - ±1 LSB INL and ±0.5 LSB DNL

(2) Offset error - <5µV with chopper-stabilized op-amps

(3) Gain error - <0.01% with precision reference

(4) Noise - 8nV/√Hz enabling microvolt-level resolution

(5) Drift - <0.05ppm/°C with proper design. Overall system accuracy of 0.01% is achievable with careful PCB layout and calibration. Contact LiTong FAE for accuracy optimization guidance.

How do I minimize noise in precision measurements?

Noise minimization techniques: (1) Shielding - use shielded cables and enclosures

(2) Filtering - implement appropriate analog and digital filtering

(3) Grounding - use star grounding and minimize ground loops

(4) Layout - keep analog traces short and away from digital signals

(5) Power - use clean power supplies with adequate decoupling. The solution achieves 8nV/√Hz noise density. For best results, implement anti-aliasing filter with cutoff at 0.5x sampling rate. Contact LiTong FAE for noise analysis support.
