It shoves 150 Mbps through each channel with a 3000 Vrms isolation barrier, which puts it squarely in the sweet spot for industrial fieldbus isolation (Profibus, CAN, RS-485) and high-speed digital links where you need galvanic separation without the throughput penalty of optocouplers. ## 75 kV/µs CMTI — the spec that keeps data clean in a noisy environment Common-mode transient immunity of 75 kV/µs (minimum) is the number that matters when this isolator sits between a microcontroller and a motor-drive power stage or an inverter phase leg. Those fast-switching edges from the IGBT or SiC FET can couple several kilovolts per microsecond across the barrier; if the CMTI is too low, you get bit flips or latch-up. At 75 kV/µs, this part has enough margin for most industrial drives and even some automotive traction inverters. The 2.5 ns typical rise/fall time and 13 ns max propagation delay keep the signal integrity tight for timing-critical loops like PWM gating or encoder feedback. ## 16-QSOP — footprint and layout reality It's a surface-mount part, so reflow is the assembly path. No isolated power on-chip — the ADUM140E1BRQZ-RL7 is a signal isolator only; you still need a separate DC-DC converter or an isolated module to power the secondary side if the application requires isolated power. The unidirectional channel configuration (4 inputs on side 1, 0 on side 2) means all four channels run the same direction — useful for SPI, UART, or parallel data buses where the data flows one way. ## Lifecycle and compliance — no end-of-life surprises It is ROHS3 compliant, which clears the environmental requirements for EU-market equipment and most global OEM specs.","metaTitle":"ADUM140E1BRQZ-RL7 iCoupler Digital Isolator, 150 Mbps, 4-Ch","metaDescription":"ADI ADUM140E1BRQZ-RL7 iCoupler digital isolator: 150 Mbps data rate, 3000 Vrms isolation, 4 unidirectional channels, -40°C to 125°C.

The ADUM140E1BRQZ has all four channels configured as inputs on side 1 with no outputs on side 2 (4/0 unidirectional), while the ADUM140E0BRQZ has a different channel direction arrangement. Both share the same 150 Mbps data rate, 3000 Vrms isolation, and 16-QSOP package. The choice depends on which side of the isolation barrier your data flows from."},{"question":"Can ADUM140E1BRQZ be used for I2C isolation?","answer":"No, the ADUM140E1BRQZ is a unidirectional isolator with all four channels running the same direction (4 inputs on side 1, 0 on side 2). I2C is a bidirectional bus that requires data to flow in both directions on the same line, which this part cannot support. For I2C isolation, you would need a dedicated bidirectional isolator or a part with configurable direction channels."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/analog-devices/ADUM140E1BRQZ-RL7","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/analog-devices/ADUM140E1BRQZ-RL7 when reusing this data.
