The ADuM1410, ADuM1411, and ADuM1412 are quad‑channel digital isolators with up to 10 Mbps data rates, low power consumption, and 105 °C operating temperature.
These quad‑channel digital isolators use Analog Devices’ iCoupler® technology to provide bidirectional communication, level translation between 3 V and 5 V, and high common‑mode transient immunity. They are suited for general‑purpose multichannel isolation, SPI interfaces, and industrial field‑bus isolation.
The datasheet details electrical characteristics for 5 V, 3 V, and mixed‑voltage operation, including supply current, propagation delay, pulse‑width limits, and power‑consumption curves. Package information, regulatory approvals, and ordering guidance are also provided.
| Supply Voltage Range (5 V operation) | 4.5 V ≤ VDD1 ≤ 5.5 V, 4.5 V ≤ VDD2 ≤ 5.5 V |
|---|---|
| Supply Voltage Range (3 V operation) | 2.7 V ≤ VDD1 ≤ 3.6 V, 2.7 V ≤ VDD2 ≤ 3.6 V |
| Input Supply Current per Channel (quiescent) | 0.50 mA typical |
| Output Supply Current per Channel (quiescent) | 0.38 mA typical |
| Common‑Mode Transient Immunity | ≥25 kV/µs |
Typical quiescent input current is 0.50 mA per channel.
The isolators provide at least 25 kV/µs common‑mode transient immunity.
