ADM3252EABCZ - Isolated USB Dual-Channel Transceiver

The ADM3252EABCZ is a state-of-the-art, high-speed, 2.5 kV fully isolated, dual-channel USB transceiver module from Analog Devices Inc. This innovative product provides a robust USB interface with isolation between the USB host controller and the USB device. It is designed to ensure reliable data communication in harsh industrial environments where electromagnetic interference (EMI) and ground loops can compromise data integrity.

The device integrates Analog Devices' iCoupler® technology to combine high-speed CMOS and monolithic air core transformer technology, which provides significant advantages over optocoupler-based solutions. This technology enables the ADM3252EABCZ to operate at USB 2.0 full-speed rates of 12 Mbps with low power consumption and minimal propagation delay.

The ADM3252EABCZ comes in a compact, surface-mount, 16-lead, wide-body SOIC package, making it suitable for space-constrained applications. The module features an ESD protection of ±15 kV on the USB transceiver to safeguard against electrostatic discharges. Additionally, it operates over a wide temperature range of -40°C to +85°C, ensuring reliable performance in extreme conditions.

This product is ideal for industrial applications that require USB connectivity with reinforced isolation, such as industrial PCs, USB port hubs, and test equipment. The isolation barrier not only protects the hardware but also ensures the safety of sensitive control electronics from high voltage spikes and transients.

Key features of the ADM3252EABCZ include:

• Integrated isolated DC-to-DC converter
• 2.5 kV RMS isolation for 1 minute per UL 1577
• USB 2.0 full-speed compatible
• Low power consumption
• ±15 kV ESD protection on USB data lines
• Compact 16-lead SOIC package
• Wide operating temperature range

With its robust design and advanced features, the ADM3252EABCZ is a top choice for engineers looking to incorporate USB interfaces in industrial and medical applications that demand high isolation and immunity to electrical noise.
