Digital isolators feature robust insulation
Avago Technologies
ACML-74x0 range
Avago Technologies has announced the ACML-74x0 range of digital isolators, which is based on patented magnetic coupler technology that enables low power consumption at high data rates of 100MBaud.
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 environments involved in test and measurement, medical imaging and industrial applications.
The ACML-74x0 range’s insulation is UL recognised at 5.6kVRMS for one minute, which Avago claims is 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.
