Introduction
The ADuM1240/ADuM1241/ADuM1245/ADuM1246 are micropower, dual-channel digital isolators based on iCoupler technology. These isolation devices integrate high-speed CMOS with monolithic air-core transformer technology, delivering superior performance characteristics compared to alternative devices such as optocouplers. The 20-pin SSOP versions of the ADuM1240/ADuM1241/ADuM1245/ADuM1246 provide control over the internal refresh function. In standard operating mode, when ENₓ = 0 (internal refresh enabled), the current per channel is less than 10 μA; when ENₓ = 1 (internal refresh disabled), the current per channel drops below 1 μA. The 20-pin SSOP versions of the ADuM1240/ADuM1241/ADuM1245/ADuM1246 provide 3.75 kV reinforced isolation, while the 8-pin SOIC versions provide 3 kV basic isolation. These devices meet regulatory requirements such as UL and CSA standards. In addition to space-saving package options, the ADuM1240/ADuM1241/ADuM1245/ADuM1246 can operate from supplies as low as 2.25 V. All models feature low pulse width distortion of less than 8 ns. Furthermore, each model includes an input glitch filter to prevent interference from spurious noise.
Features
- Ultra-low power operation
- Supply voltage: 3.3 V, 5.6 μA (quiescent current per channel, refresh enabled), 0.3 μA (quiescent current per channel, refresh disabled), 148 μA/Mbps (typical dynamic current per channel)
- Supply voltage: 2.5 V, 3.1 μA (quiescent current per channel, refresh enabled), 0.1 μA (quiescent current per channel, refresh disabled), 116 μA/Mbps (typical dynamic current per channel)
- 20-pin miniature SSOP package and 8-pin miniature SOIC package
- Bidirectional communication
- Data rates up to 2 Mbps (NRZ)
- Operating temperature up to: 125°C
- High common-mode transient immunity: >25 kV/μs
- Safety and regulatory approvals: UL 1577 component recognition program (pending), per UL 1577, 1-minute 3750 V rms (20-pin SSOP), per UL 1577, 1-minute 3000 V rms (8-pin SOIC), CSA component acceptance notice 5A (pending), VDE certificate of conformity (pending), DIN V VDE V 0884-10 (VDE V 0884-10): 2006-12, V₁ₒᵣₘ = 849 V peak (20-pin SSOP), V₁ₒᵣₘ = 560 V peak (8-pin SOIC)
Applications
- General-purpose low-power multi-channel isolation
- 1 MHz low-power SPI
- 4 mA to 20 mA loop process control
