The ADUM5400ARWZ integrates four unidirectional digital isolation channels with an IsoPower DC-DC converter in a 16-SOIC package. It provides signal isolation and an isolated power output from a single 5V supply rail.
At 1Mbps, this isolator handles isolated SPI, UART, and GPIO signaling. The 100ns max propagation delay and 40ns pulse-width distortion keep timing skew tight for control-loop interfaces.
Yes, the ADUM5400ARWZ integrates an IsoPower DC-DC converter that generates an isolated power output from the 5V input supply, eliminating the need for a separate isolated DC-DC module.
The ADUM5400ARWZ has all four channels oriented input-side-1 to side-2 (4/0), while the ADUM5401ARWZ (not in this listing) typically has a 3/1 channel direction split. Both share the same 2500Vrms isolation, 1Mbps data rate, and SOIC-16 package. The channel direction determines which side receives data, so choose based on your signal flow requirements.
