It is a general-purpose part — no integrated DC-DC converter — sized for isolating SPI, UART, GPIO, or PWM lines in industrial fieldbus, motor-drive feedback, and isolated sensor interfaces. The 150 Mbps data rate keeps propagation delay to 13 ns max (each direction), with 2.5 ns typical rise/fall and 3 ns pulse-width distortion, so it handles high-speed clock and data links without skew eating into your timing budget. The 75 kV/µs common-mode transient immunity (CMTI) is the spec that matters when you are isolating a controller from a noisy inverter phase leg or a switching power stage — it means the output does not glitch when the ground plane jumps several hundred volts in a microsecond. ## Supply, temperature, and package — fit for industrial and automotive environments Package is a standard 16-pin SOIC with 3.90 mm body width, footprint-compatible with many older 16-SOIC isolators. No isolated power on chip — you supply the secondary-side rail externally or add a separate isolated DC-DC module. For a production BOM, that means no last-time-buy math needed and no forced redesign window. ## Channel-directional layout — 3/1 input split Three channels are configured as Side-1 inputs / Side-2 outputs, one channel is Side-2 input / Side-1 output. That 3/1 split fits the typical isolated SPI or UART link: three lines from controller to peripheral (SCLK, MOSI, CS) plus one return line (MISO) back to the controller. If your application needs a different direction balance — say 2/2 for two bidirectional data pairs — the ADUM142D1BRQZ or ADUM142E0BRZ in the same iCoupler family offer that, with identical speed and isolation ratings.","metaTitle":"ADUM141E1BRZ Digital Isolator, 150Mbps, 3000Vrms, 4-Ch","metaDescription":"ADUM141E1BRZ iCoupler 4-channel digital isolator, 150Mbps data rate, 3000Vrms isolation, 1.7V-5.5V supply, -40C to 125C.

Rise and fall times are 2.5 ns typical. Pulse-width distortion is 3 ns max. At 150 Mbps, the part keeps signal edges clean for high-speed links like SPI at 50 MHz+."},{"question":"Does ADUM141E1BRZ require an external power supply?","answer":"The isolator itself does not generate an isolated secondary-side rail. You must supply power to both VDD1 and VDD2 separately. For designs needing an integrated isolated DC-DC, look at ADI's isoPower series (e.g., ADuM5xxx family)."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/analog-devices/ADUM141E1BRZ","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/analog-devices/ADUM141E1BRZ when reusing this data.
