Digital isolators are electrical devices used to transfer data signals across an isolation barrier without direct electrical connection. The ADUM6202ARWZ-RL is a bidirectional digital isolator with an optically coupled integrated circuit (IC) that combines excellent dynamic isolation performance, 20 kV/µs, proportional to temperature, with high data rates up to 1 Mbit/s. It is designed to provide isolated data transmission in an integrated package with small footprint.

The ADUM6202ARWZ-RL is designed for isolated data transmission with quiet, low-distortion channel-to-channel isolation. It is bidirectional, integrated optically coupled isolator IC with four channels, delivering: one forward logic channel, one local/enable logic channel, one inverted logic channel, and one return path enable (RPE) logic channel. The RPE logic channel provides a logic-level voltage reference to the sense pins, eliminating the need for a separate voltage supply to each channel.

The ADUM6202ARWZ-RL features an Automatic Data Rate Adjustment (ADRA) technology that allows data transfer rates up to 1 Mbit/s. With this technology, the switching speed of each channel dynamically adapts to the speed of its host data signal, thus, reducing the power consumption of the device. As a result, the ADUM6202ARWZ-RL delivers reliable, low-power data transfer with improved signal integrity.

The ADUM6202ARWZ-RL digital isolator also features: on-board EDD (electrical discharge device), capable of controlling up to 20 kHz/Vrms, 0.15 A of peak output current (at 5V supply voltage, 50V DV), adjustable receiver hysteresis of ±15%.

The ADUM6202ARWZ-RL is well suited for industrial, automotive, consumer, and medical applications where data transmission needs to be isolated from the original source. It is also suitable for various motor control applications, such as controlling servo motors, stepper motors, and brushless motors. In addition, the ADUM6202ARWZ-RL can be used to provide isolation for high-speed digital communication links between two or more processor nodes, such as voice, video, data, or signal transmission.

The ADUM6202ARWZ-RL digital isolator is capable of detecting, isolating, and communicating digital signals with a bandwidth of up to 1 Mbit/s. It features an automatic data rate adjustment technology that reduces power consumption and improves signal integrity, while providing a low propagation delay of typically 50 to 100 ns. The device is capable of providing highly reliable, low-power data transmission, which makes it well suited for high-speed data communication applications, such as motor control and communication between two or more processor nodes.
