Precision op-amps are used to achieve high gain with minimal added noise, ensuring that the full dynamic range of the ADC is utilized without saturation or signal loss. Key considerations include gain stability, bandwidth, and input offset voltage to maintain signal fidelity.

• Filtering Techniques
  Noise is ubiquitous in electronic systems, originating from power supplies, electromagnetic interference (EMI), and sensor non-idealities. Our boards employ multi-stage filtering, including anti-aliasing filters before the ADC to prevent aliasing errors and digital filters post-conversion to remove high-frequency noise components. This ensures that only the true signal is processed, leading to cleaner and more accurate measurements.

• Multiplexing
  For systems requiring measurement from multiple points, multiplexers are often employed. These allow a single ADC to sequentially sample various input channels, optimizing resource utilization and reducing component count. Careful design ensures minimal crosstalk and consistent sampling rates across all channels, preserving measurement synchronization.
