ADUM1200Dual-Channel Digital Isolator (2/0 Channel Directionality) | Isolators | 24 | Active | The ADuM1200 is a dual-channel, digital isolator with 2/0 directionality based on the Analog Devices, Inc.,iCoupler®technology. Combining high speed CMOS and monolithic transformer technologies, this isolation component provides outstanding performance characteristics superior to alternatives, such as optocouplers.By avoiding the use of LEDs and photodiodes,iCoupler devices remove the design difficulties commonly associated with optocouplers. The typical optocoupler concerns regarding uncertain current transfer ratios, nonlinear transfer functions, and temperature and lifetime effects are eliminated with the simpleiCoupler digital interfaces and stable performance characteristics. The need for external drivers and other discrete components is eliminated with theseiCoupler products. Further-more,iCoupler devices consume one-tenth to one-sixth the power of optocouplers at comparable signal data rates.The ADuM120x family of isolators provides two independent isolation channels in a variety of channel configurations and data rates (see the Ordering Guide). Both parts operate with the supply voltage on either side ranging from 2.7 V to 5.5 V, providing compatibility with lower voltage systems as well as enabling a voltage translation functionality across the isolation barrier. In addition, the ADuM120x provide low pulse width distortion (<3 ns for CR grade) and tight channel-to-channel matching (<3 ns for CR grade). Unlike other optocoupler alternatives, the ADuM120x isolators have a patented refresh feature that ensures dc correctness in the absence of input logic transitions and during power-up/power-down conditions.ADuM1200W and ADuM1201W are automotive grade versions qualified for 125°C operation per AEC-Q100. See the Automotive Products section for more details.APPLICATIONSSize-critical multichannel isolationSPI interface/data converter isolationRS-232/RS-422/RS-485 transceiver isolationDigital field bus isolationHybrid electric vehicles, battery monitor, and motor driveThe ADuM1200-EP supports defense and aerospace applications (AQEC) |

ADUM1233Isolated, Precision Half-Bridge Driver, 0.1 A Output | Isolators - Gate Drivers | 2 | Active | The ADuM1233 is an isolated, half-bridge gate driver that employs the Analog Devices, Inc.,iCoupler®technology to provide independent and isolated high-side and low-side outputs. Combining high speed CMOS and monolithic transformer technology, this isolation component provides outstanding performance characteristics superior to optocoupler-based solutions.By avoiding the use of LEDs and photodiodes, thisiCoupler gate drive device is able to provide precision timing characteristics not possible with optocouplers. Furthermore, the reliability and performance stability problems associated with optocoupler LEDs are avoided.In comparison to gate drivers employing high voltage level translation methodologies, the ADuM1233 offers the benefit of true, galvanic isolation between the input and each output. Each output can be operated up to ±700 VPEAKrelative to the input, thereby supporting low-side switching to negative voltages. The differential voltage between the high side and low side can be as high as 700 VPEAK.As a result, the ADuM1233 provides reliable control over the switching characteristics of IGBT/MOSFET configurations over a wide range of positive or negative switching voltages.ApplicationsIsolated IGBT/MOSFET gate drivesPlasma displaysIndustrial invertersSwitching power supplies |
