Driving Smarter Data Acquisition: DSown Technology's High-Precision ADC DADS1220/1120

With the rapid development of industrial automation, medical electronics, HVAC (heating, ventilation, and air conditioning) systems, and automotive R&D, high-performance analog-to-digital converters (ADCs) have become critical components. In ADAS (Advanced Driver Assistance Systems) and sensor evaluation, weak analog signals from sensors must be converted to digital signals by high-precision ADCs for accurate processing—making the ADC the “neural center” of smart sensing systems.

DSown Technology’s high-precision ADCs, DADS1220/1120, are pin-to-pin compatible with classic international models while offering equivalent performance and seamless replacement. They provide a reliable, cost-effective, and high-efficiency solution for system designers seeking high-precision ADCs for prototyping and industrial applications.

Even consumer and mid-range vehicle electronics, such as dash cams, driver-assistance prototypes, and ADAS sensor evaluation systems, can benefit from high-precision ADCs at the R&D or prototyping stage. While mass-production ADAS or safety-critical ECUs require AEC-Q100 certified components, non-AEC-Q100 ADCs like DADS1220/1120 are ideal for prototyping, sensor evaluation, and algorithm testing, allowing engineers to validate vehicle electronics and sensing functions efficiently.

In HVAC systems, precise temperature and environmental sensing is crucial for energy efficiency, comfort, and safety. High-resolution ADCs enable accurate acquisition of thermistors, RTDs, or other environmental sensors, ensuring reliable system control and long-term stability.

DADS1220/1120 also excel in industrial automation and medical devices, accurately capturing low-level signals from pressure sensors, thermocouples, strain bridges, or physiological sensors.

The DADS1220/1120 are 24-/16-bit high-precision Σ-Δ ADCs designed for low-speed, high-accuracy sensor data acquisition. They are ideal for applications including:

• Automotive R&D / Sensor prototyping (non-production).
• Industrial automation (RTD, thermocouple, strain bridge measurement).
• Medical equipment (physiological signal acquisition).
• Smart instruments, environmental monitoring, and HVAC systems.

Pin-to-Pin Compatibility with Classic Models 1220/1120 No PCB redesign or major software adjustment needed; zero adaptation cost.

24-bit Resolution, 20-bit Effective Number of Bits (ENOB) Capture microvolt-level signal variations with high reliability.

Integrated Low-Noise PGA (Gain 1–128) Automatically adapts to sensor output range, maximizing ADC dynamic range.

Dual Programmable Excitation Current Sources Easily drive RTDs, thermistors, and other passive sensors.

On-Chip Precision Temperature Sensor + Internal Reference Supports environmental compensation for long-term stability and measurement consistency.
