Avago launches high-speed digital isolator family


Avago Technologies announced a family of digital
isolators that deliver the market’s most robust insulation performance.



The new ACML-74×0
family is based on patented magnetic coupler technology that enables low power
consumption at high data rates of 100 MBaud.



The CMOS digital isolators feature thick, multi-layer
insulation that is robust to very high voltage transient and working voltage,
providing the reinforced insulation required for the harsh operation
environments facing test and measurement, medical imaging and industrial



The ACML-74×0 family’s robust insulation is UL recognized
at 5.6 kVRMS for 1 minute, the highest of any digital isolators,
enabling existing equipment to rate to higher voltages or provide greater
safety margins in high voltage environments.



During data transmission, the devices send low current
pulses across the isolation barrier, maintaining low electromagnetic
interference (EMI) emissions even at high data rates. This low EMI performance
also provides end-applications with stronger ability to pass regulatory
testing. The isolators integrate a quad-channel structure, and offer uni- or
bi-directional configurations, to provide PCB savings.



The ACML-7400 device offers an all-in-one channel
configuration, the ACML-7410 offers a bi-directional 3/1 channel configuration,
and the ACML-7420 offers a bi-directional 2/2 channel configuration. The
ACML-74×0 isolators are all available in 16-pin SOIC wide-body packages, and
are priced starting at $6.48 each in 1,000 piece quantities.
