ISO3082DW 2/2 Transceiver, Isolated Half RS422, RS485 16-SOIC
The ISO3082DW is a high-performance dual-channel digital isolator manufactured by Texas Instruments (TI), designed to provide robust electrical isolation between two circuits while maintaining signal integrity. Built on TI’s proprietary capacitive isolation technology, this chip supports a 5 kV RMS isolation rating and operates across a wide temperature range (-40°C to +125°C), making it suitable for industrial automation, motor drives, and medical equipment. It features two independent isolation channels, each capable of transmitting data at speeds up to 150 Mbps, with a propagation delay of just 9 ns (typical). The ISO3082DW is available in a compact 8-pin SOIC package, ensuring easy integration into space-constrained PCB designs.
ISO3082DW Applications
The ISO3082DW is widely used in industrial control systems, such as PLCs and field transmitters, where galvanic isolation is required to protect sensitive electronics from high-voltage noise and surges. In motor drive applications, it isolates PWM control signals from power stages, enhancing system reliability. The chip is also deployed in medical devices (e.g., patient monitors) to ensure patient safety by preventing electrical leakage between isolated circuits. Additionally, its high-speed capabilities make it suitable for communication interfaces like RS-485 and CAN buses in automotive and aerospace systems.
