Digital Isolator Product Selection and Resource Guide Performance • Integration • Efficiency • Reliability • Safety Digital isolators with iCoupler® technology enable designers to implement isolation in designs without the cost, size, power, performance, and reliability constraints found with optocouplers. iCoupler digital isolators also meet the wide range of creepage/clearance requirements and are the industry’s only digital isolators with certified 8 mm creepage. With more than half a billion channels shipped into the field, these magnetically isolated products meet the same rigid safety standards as optocouplers. Advantages of the Broadest Portfolio of Digital Isolators Performance 4× improvement in data rate and timing specifications. Integration Multiple isolation channels integrated with other functions reduce size, cost, and design complexity. Power Consumption Operates at power levels up to 90% lower than optocouplers. Portfolio Offerings • Single and multichannel data isolators • I2C ® digital isolators • Digital isolators with isolated power: isoPower ® • Isolated RS-485 transceivers • USB isolators • Isolated gate drivers www.analog.com/icoupler • Isolated CAN transceivers • Isolated RS-232 transceivers • Isolated Σ-∆ modulators Ease of Use Standard digital CMOS interfaces mean no external components needed to connect to other digital devices. Reliability Eliminates LED wearout traditionally found in optocouplers. Safety Meets same rigid safety standards as optocouplers, including reinforced insulation. 1-Channel Digital Isolators Reverse Direction Options Isolation Rating (kV rms) Part Number ADuM1100 ADuM3100 0 • • 2.5 2.5 1 2 Output Default H L • • Max Data Rate (Mbps) 3 25, 100 25, 50 EN Z Max Temperature (°C) Package 105, 125 105 8-lead SOIC_N 8-lead SOIC_N 2-Channel Digital Isolators Reverse Direction Options Part Number 1 kV rms Isolation ADuM724x 2.5 kV rms Isolation ADuM120x* ADuM1210 ADuM128x ADuM320x* ADuM321x* 5 kV rms Isolation ADuM220x* ADuM221x* 2 Output Default H L Max Data Rate (Mbps) 0 1 3 • • 1, 25 • • • • • • • 1, 10, 25 10 1, 25, 100 1, 10, 25 1, 10 • • • • • 1, 10 1,10 • • • Max Temperature (°C) Package 105 8-lead SOIC_N • 105, 125 105 125 105, 125 105, 125 8-lead SOIC_N 8-lead SOIC_N 8-lead SOIC_N 8-lead SOIC_N 8-lead SOIC_N • 105 125 16-lead SOIC_W/16-lead SOIC_IC 16-lead SOIC_W/16-lead SOIC_IC EN Z • • • • 3-Channel Digital Isolators Reverse Direction Options Isolation Rating (kV rms) Part Number 0 • • • 2.5 2.5 2.5 ADuM130x* ADuM131x ADuM330x 1 • • • 2 Output Default H L • • • • Max Data Rate (Mbps) 3 1, 10, 90 1, 10 1, 10, 90 EN Z • Max Temperature (°C) Package 105, 125 105 105 16-lead SOIC_W 16-lead SOIC_W 16-lead SOIC_W • 4-Channel Digital Isolators Reverse Direction Options Part Number 1 kV rms Isolation ADuM744x 2.5 kV rms Isolation ADuM140x* ADuM141x ADuM340x* ADuM344x 5 kV rms Isolation ADuM240x ADuM440x Max Data Rate (Mbps) 3 Output Default H L EN Z Max Temperature (°C) Package • 105 16-lead QSOP 105 105 105 105 16-lead SOIC_W 16-lead SOIC_W 16-lead SOIC_W 16-lead SOIC_W 105 105 16-lead SOIC_W/16-lead SOIC_IC 16-lead SOIC_W/16-lead SOIC_IC 0 1 2 • • • 1, 25 • • • • • • • • • • • • • 1, 10, 90 1, 10 1, 10, 90 150 • • • • • • • • • • 1, 10, 90 1, 10, 90 • • • • • 5-Channel Digital Isolators Reverse Direction Options Part Number 0 1 kV rms Isolation ADuM7510 2.5 kV rms Isolation ADuM1510 1 2 Output Default H L Max Data Rate (Mbps) 3 EN Z Max Temperature (°C) Package • 10 • 105 16-lead QSOP • 10 • 105 16-lead SOIC_W 6-Channel Digital Isolator Reverse Direction Options Isolation Rating (kV rms) Part Number ADuM764x 1 • 1 2 • Max Data Rate (Mbps) 3 • 1, 25 Output Default H L • EN Z Max Temperature (°C) Package 105 20-lead QSOP Digital Isolators with Isolated Power, isoPower Part Number 2.5 kV rms Isolation ADuM5000 ADuM520x* ADuM524x ADuM540x* 5 kV rms Isolation ADuM6000 ADuM620x ADuM640x Total Number of Data Channels Reverse Direction Options 0 1 2 3 0 2 2 4 • • • • • • • • • 0 2 4 • • • • • • • • Max Data Rate (Mbps) Isolated Supply Output | www.analog.com/icoupler Package 3.3 or 5.5 3.3 or 5.5 4.5 or 5.5 3.3 or 5.5 105 105 105 105 16-lead SOIC_W 16-lead SOIC_W 8-lead SOIC_N 16-lead SOIC_W 3.3 or 5.5 3.3 or 5.5 3.3 or 5.5 105 105 105 16-lead SOIC_W/16-lead SOIC_IC 16-lead SOIC_W/16-lead SOIC_IC 16-lead SOIC_W/16-lead SOIC_IC Range (V) • 1, 25 1 1, 25 100 100 10 100 • 1, 25 1, 25 100 100 100 *AEC-Q100 qualified models available for use in automotive applications.
