Welcome Here  Shenzhen Mingjiada Electronics Co., Ltd.

In the era of rapid development of industrial automation, new energy and medical equipment, electrical isolation technology has become a core pillar for ensuring system safety and enhancing signal reliability. Shenzhen Mingjiada Electronics Co., LTD., relying on its global supply chain resources, has built a one-stop supply platform for ADI digital isolators covering all scenarios and specifications. From basic dual-channel isolation to high-performance multi-channel solutions, Mingjiada, with its million-level inventory reserves, original factory genuine product guarantee and scenario-based technology empowerment, helps enterprises break through the design bottlenecks of electrical noise, ground potential difference and safety isolation.

I. ADI iCoupler® Technology: The performance Benchmark in the field of digital isolation

ADI's iCoupler® technology replaces the traditional optocoupler's photoelectric conversion with a single-chip air-core transformer and integrates high-speed CMOS technology to achieve three revolutionary breakthroughs:

Ultra-low signal delay: The propagation delay is as low as 6.2ns (such as ADUM342E0WBRQZ), which is more than 10 times faster than optocouplers, meeting the timing accuracy requirements of real-time control systems.

Outstanding anti-interference performance: Common-mode transient immunity up to 100 kV/µs (such as the ADUM240D series), completely eliminating the influence of high-voltage transient noise in motor drives and inverters.

Wide voltage and temperature adaptability: Supports a wide voltage input range of 1.71V to 5.5V, and operates within a temperature range of -40 ° C to +125 ° C, making it suitable for the harsh environments of automotive electronics and industry.

Ii. Core Product Matrix: Matching multi-scenario isolation requirements

1. Multi-channel universal isolator: High integration design simplifies system architecture

Four-channel flagship series

ADUM3402WBRWZ: 90Mbps high-speed transmission, integrated four-channel isolation, support for SPI/RS-485 bus isolation, built-in enhanced ESD protection, making it the preferred choice for industrial fieldbus.

ADUM240D series: 150 Mbps ultra-fast communication (ADUM240D0BRWZ, etc.), resistant to 5kVrms isolation voltage, channel matching accuracy up to 3ns, suitable for photovoltaic inverters and servo drives.

Dual-channel precision model

ADUM2280BRIZ/ADUM2286BRIZ: 5 KVRMS isolation pressure, support one-way or two-way channel configuration, the default high/low level output optional, simplify the power control logic design;

ADUM1200CRZ: 150 Mbps ultra-high speed, 35kV/µs immunity, providing anti-interference guarantee for CAN FD bus.

2. Specialized Protocol isolator: Addressing industry pain points

I²C bus isolation scheme

ADUM125x series: It features an original "unidirectional clock + bidirectional data" architecture (such as ADUM1255AWA), supporting hot plugging and VOL levels as low as 0.4V, resolving clock contention and level conflicts in multi-node I²C communication.

Ultra-low power consumption design (only 142μA per channel at 400kHz) extends the lifespan of battery devices and is widely used in BMS and medical sensors.

RS-485 isolation integration solution

ADM2587EBRWZ: A rare "signal + power" fully integrated isolation solution in the industry, with an internal DC-DC converter, eliminating the need for an external power module. ±15kV ESD protection directly enhances the reliability of industrial communication ports.

3. High-voltage and automotive-grade isolators: Safety compliance benchmarks

ADUM342E0WBRQZ: 5.7kV RMS isolation voltage, 180kV/µs immunity, certified by AEC-Q100, meeting the safety standards for OBC and battery management systems of electric vehicles;

ADUM2401CRWZ: With 90Mbps high-speed transmission and full temperature range operation from -40℃ to 125℃, it is an ideal choice for motor drives and charging pile control boards.

Iii. Mingjiada Supply System: Full-chain Guarantee from technology Selection to Agile Delivery

1. Double guarantee of genuine products and deep inventory

100% original factory traceability: All isolators are provided with complete batch codes and original factory packaging, supporting UL and VDE certification document verification to eliminate the risk of refurbishment.

Million-level dynamic inventory: Shenzhen bonded warehouse always keeps over 500,000 ADI isolators in stock, covering scarce models such as ADUM1200 and ADUM3402. Urgent orders are supported for 24-hour direct air shipment.

2. Price optimization and flexible services

Cost control advantage: Relying on ADI's direct supply channel, the purchase price for medium and small batches is 5% to 15% lower than the market price, and it supports engineering samples with a minimum order of 10 pieces (such as ADUM1280WARZ).

VMI inventory management: On-demand material invocation reduces customer capital occupation, and slow-moving inventory can be recycled in reverse.

Conclusion: Rebuilding the foundation of smart hardware with security isolation technology

Mingjiada Electronics provides one-stop services from selection to delivery for Chinese enterprises by integrating ADI's full range of isolation solutions, original factory-level testing capabilities and a global logistics network. Whether dealing with industrial noise, automotive electrical environments or medical safety regulations, there is always an isolation solution here to safeguard the safety of your signal chain.
