High-speed and high-reliability performance for stable USB data transmission. Purifies surges and noise interferences from USB transmission, ensuring a cleaner audio experience. Functions as a USB repeater, relaying USB devices over long distances. Supports USB 2.0 (Full Speed) and (Half Speed) for versatile compatibility. Operating temperature range of -40℃ to 125℃, suitable for industrial applications and environments. The ISOUSB211 chip is mainly used to purify various surges and noise interferences brought by USB transmission. It can provide a more stable data transmission environment for USB audio devices and isolate power interference that enters through the device GND. Besides purification, it is also a USB repeater. It is very suitable for PC HIFI and car users. Isolation voltage: 1500V. Transient common-mode interference resistance > 100kV. Product size: 80*35*26mm. Weight: 80g. Two power supply methods: 1. Self-powered by the upstream USB device. 2. A high-quality power supply can be connected through the DC-5.5 2.1 power interface for enhanced power supply. The isolated power module can only provide a current of 150mA. The dac requires a relatively high usb power supply current and needs to be connected to an external dc5V power supply.
