Evolution of High-Precision ΔΣ ADC
1. ADC Overview
An Analog-to-Digital Converter (ADC) is a critical component that converts continuously varying analog signals into discrete digital signals. In modern electronic systems, almost all processes involving “sensing → processing → control” rely on ADCs as the core bridge for signal conversion.
In embedded system architectures, ADCs are generally categorized into two types:
• MCU-integrated ADCs (On-chip ADC)
• External standalone ADCs (External ADC)
Generally speaking, the differences in their applications are as follows:
When system requirements reach 16-bit or 24-bit resolution and above, along with low noise and high linearity, external ADCs become the inevitable choice.
Megawin Technology launched the MAD2402 (24-bit Delta-Sigma ADC) last year, targeting the low-to-mid-speed, high-precision measurement market. Typical applications include: electronic scales, body fat scales, medical devices (blood pressure monitors, glucose meters), handheld instruments, and industrial transmitters.

5. Chip Compatibility and Replacement Advantages
The MAD series is designed to benchmark mainstream products and offers strong replacement capability. For example:
•MAD2418 ↔ ADS1256 (TI)
👉Nearly pin-to-pin compatible with comparable performance
🔹 Strategic Significance:
• Reduces customer switching costs
• Shortens design-in time
• Provides a more competitive cost solution
6. Conclusion
The launch and upgrade of the MAD series demonstrate that Megawin Technology has evolved from a cost-driven alternative provider into a company offering a comprehensive ADC portfolio, covering low-speed to mid-speed and high-precision measurement needs.
In particular, the MAD2418, with its 23-bit ENOB, is approaching the performance level of leading international manufacturers in key metrics such as noise, dynamic range, and linearity.
Combined with high compatibility with mainstream models, the MAD series helps lower adoption barriers and accelerate market penetration, showing strong growth potential in industrial automation and medical electronics sectors.
