Optimising ADC Gain in Data Acquisition — Why DualCoreADC® Matters
The Problem: Fixed Gain Limits Accuracy or Overloads the System
In many test applications, engineers must measure signals that occasionally sit below 5 V but can also spike toward 100 V. A standard Analog-to-Digital Converter (ADC) gain setting creates a trade-off:
- If the ADC range is set to 0–5 V, any signal exceeding that will clip and overload
- If the ADC range is set to 0–100 V, low-level signals will lose resolution and precision
Using multiple channels at different gains is inefficient — it increases hardware requirements and complicates analysis.
The Solution: Dewesoft DualCoreADC® Technology
Dewesoft solves this limitation with DualCoreADC®, a patented technology that uses two independent 24-bit ADCs per channel. Each ADC measures the same input at different gain levels in real time and combines the data into a single seamless channel.
This design ensures:
- High voltage events are captured without overload
- Low-level signals are recorded with full resolution
- No manual switching or duplicate channels are required
- Compatible even with slow-changing signals such as thermocouples
Performance Advantages in Dewesoft SIRIUS DAQ Systems
With DualCoreADC®, Dewesoft SIRIUS DAQ platforms deliver exceptional measurement performance:
- >130 dB signal-to-noise ratio
- >160 dB dynamic range
- Up to 200 kS/s per channel
- Up to 20× less noise than typical 24-bit DAQ systems
This allows precise high-dynamic-range acquisition without sacrificing safety or resolution.
Need Hybrid Capability With Higher Sample Rates?
Some applications require both:
- Channels with ultra-high dynamic range and anti-aliasing, and
- Separate channels with much higher sampling speeds
Dewesoft addresses this with Hybrid ADC Technology, which combines the advantages of multiple converter architectures for mixed-signal applications. To understand this in more detail, explore Dewesoft’s overview of Hybrid ADC Technology.
