Quad-Channel Digital Isolators ADuM1400/ADuM1401/ADuM1402
FEATURES
GENERAL DESCRIPTION
Qualified for automotive applications
The ADuM1400/ADuM1401/ADuM14021 are quad-channel
Low power operation
digital isolators based on Analog Devices, Inc., iCoupler®
5 V operation
technology. Combining high speed CMOS and monolithic air
1.0 mA per channel maximum at 0 Mbps to 2 Mbps
core transformer technology, these isolation components provide
3.5 mA per channel maximum at 10 Mbps
outstanding performance characteristics superior to alternatives,
31 mA per channel maximum at 90 Mbps
such as optocoupler devices.
3 V operation 0.7 mA per channel maximum at 0 Mbps to 2 Mbps 2.1 mA per channel maximum at 10 Mbps 20 mA per channel maximum at 90 Mbps
Bidirectional communication 3 V/5 V level translation High temperature operation: 125°C High data rate: dc to 90 Mbps (NRZ) Precise timing characteristics
2 ns maximum pulse width distortion
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 simple iCoupler digital interfaces and stable performance characteristics.
The need for external drivers and other discrete components is eliminated with these iCoupler products. Furthermore, iCoupler devices consume one tenth to one sixth...
