Product details

Its 1 Mbps data rate suits general-purpose signal isolation for control lines, slow serial interfaces, and GPIO-level translation where the bus doesn't need high throughput but must withstand a voltage differential. The unidirectional channel configuration—three inputs on side 1, zero on side 2—means this part is designed to isolate signals flowing in one direction only, typical for pulling sensor readings or digital status lines across an isolation barrier.

The 3750 Vrms isolation voltage per UL 1577 is the headline safety rating. For a design that needs reinforced isolation in a medical or industrial power supply, this part meets the one-minute withstand test at that level. The 25 kV/µs common-mode transient immunity means it can reject fast voltage spikes from a motor-drive inverter or a switching power supply without corrupting the data output — a spec that matters more than the raw isolation voltage when the environment has high dV/dt events.

Frequently asked questions

How many channels does ADUM1310ARWZ-RL have and what is the input/output configuration?

Three unidirectional channels with all three inputs on side 1 and none on side 2. That means it isolates three digital signals flowing from the primary side to the secondary side only — no reverse-direction channel. If your design needs a bidirectional or mixed-direction channel, look at the ADuM1400 or ADuM1200 siblings.

What is the maximum data rate of ADUM1310ARWZ-RL?

1 Mbps. Propagation delay is 100 ns max (both tpLH and tpHL), with pulse-width distortion up to 40 ns. For a 1 MHz clock or a UART at 115.2 kbps, that timing budget is fine; for SPI at 10 MHz or faster serial protocols, step up to the ADuM1400 or ADuM1200 series rated at 10 Mbps or higher.

Is ADUM1310ARWZ-RL compatible with ADUM1310ARWZ?

Electrically identical — same die, same isolation rating, same channel count and direction. The only difference is the packaging: ADUM1310ARWZ ships in tube or cut-tape, while the -RL suffix indicates Tape & Reel for high-volume pick-and-place. Both are the same part for BOM purposes; just pick the reel option if your assembly line is set up for reeled components.
