ADuM320N/ADuM321N

5.7 kV RMS/3.0 kV RMS Dual Digital Isolators

FEATURES

GENERAL DESCRIPTION

► High common-mode transient immunity: 180 kV/µs typical

► High robustness to radiated and conducted noise

► Low propagation delay

► 6.2 ns typical (10 ns maximum) for 5 V operation

► Low dynamic power consumption, <1.65 mA/ch at 1 Mbps

► 2.25 V to 5.5 V level translation

► 150 Mbps maximum guaranteed data rate

► High temperature operation: 125°C

► Safety and regulatory approvals

► UL recognition per UL1577

► 5700 V rms (SOIC_IC)

► 3000 V rms (SOIC_N)

► VDE certificate of conformity

► V_IORM= 1173 V_PEAK(SOIC_IC)

► V_IORM= 636 V_PEAK(SOIC_N)

► CSA component certification per IEC 62368-1, IEC60601-1,

and IEC 61010-1

► TÜV SÜD component certification per EN 62368-1

► CQC component certification per GB4943.1-2022

► ±8 kV IEC 61000-4-2 ESD protection across isolation barrier

► ±4 kV HBM ESD protection on input/output pins

► Fail-safe high (N1) or low (N0) options

The ADuM320N/ADuM321N¹are dual-channel digital isolators

based on Analog Devices, Inc., iCoupler^®technology. Combining

high speed, complementary metal-oxide semiconductor (CMOS)

and monolithic air core transformer technology, these isolation

components provide outstanding performance characteristics and

meet CISPR 32/EN 55032 Class B limits at 5 Mbps. The maximum

propagation delay is 10 ns with a pulse width distortion of less

than 3 ns at 5 V operation. Channel matching is hard at 3.0 ns

maximum.

The ADuM320N/ADuM321N data channels are independent and

are available in a variety of configurations with a withstand voltage

rating of 5.7 kV RMS and 3.0 kV RMS (for more information, see

the Ordering Guide section). The devices operate with the supply

voltage on either side ranging from 2.25 V to 5.5 V, providing

compatibility with lower voltage systems as well as enabling voltage

translation functionality across the isolation barrier.

Two different fail-safe options are available, by which the outputs

transition to a predetermined state when the input power supply is

not applied.
