The ADuM4165 and ADuM4166 are USB 2.0 port isolators developed by Analog Devices Inc., designed to provide secure and reliable data transfer with galvanic isolation for USB connections. These isolators are particularly useful in environments where isolation is critical to protect against ground loops, electrical noise, and other potential interferences.
Both ADuM4165 and ADuM4166 support full-speed (12 Mbps) and low-speed (1.5 Mbps) USB data rates, ensuring broad compatibility with various USB peripherals. These devices offer robust galvanic isolation, which is essential for protecting data communication in environments with differing ground potentials or high electrical noise. The ADuM4166 includes an integrated DC-to-DC converter that provides isolated power to downstream devices, eliminating the need for an external power supply and simplifying system design. Designed for energy efficiency, these isolators have low power consumption, making them suitable for battery-powered applications and other power-sensitive systems.
Both models provide enhanced electromagnetic interference (EMI) performance, ensuring reliable operation in electrically noisy environments.
Specifications: Isolation Voltage: 2.5 kV RMS Data Rates: Full-speed: 12 Mbps Low-speed: 1.5 Mbps Supply Voltage: 3.0 V to 3.6 V Operating Temperature Range: -40°C to +105°C Package Type: 20-lead SSOP (Shrink Small Outline Package)
