Analog Devices Inc. ADUM2200BRIZ

Overview

ADUM2200BRIZ from Analog Devices is a dual-channel digital isolator using iCoupler® transformer-based isolation, providing 5 kV_rms reinforced insulation, 10 Mbps data rate, and 3 ns maximum pulse width distortion. It operates from 3.0 V to 5.5 V on both sides, supports 3.3 V/5 V level translation, and delivers ≤3.7 mA per channel at 10 Mbps under 5 V supply - used in medical equipment, motor drives, and RS-485 transceiver isolation.

For engineers reviewing the ADUM2200BRIZ datasheet, ADUM2200BRIZ pinout, ADUM2200BRIZ application, or ADUM2200BRIZ equivalent, key selection criteria include reinforced insulation rating (VIORM = 645 V_peak), channel-to-channel matching (≤3 ns), high common-mode transient immunity (>25 kV/µs), and SOIC wide-body package with enhanced creepage (RI-16-2).

Technical Context

The ADUM2200BRIZ implements monolithic air-core transformer coupling for galvanic isolation between two independent unidirectional channels, eliminating LED/photodiode aging and CTR drift. Its patented refresh circuit ensures DC correctness during idle periods and power transitions without external components.

It supports mixed-voltage operation (e.g., 5 V on Side 1 / 3.3 V on Side 2), maintains precise timing across temperature (±5 ps/°C PWD drift), and achieves <3 ns channel-to-channel skew - critical for synchronized control signals in motor gate drivers and isolated ADC interfaces.

Key Specifications

FAQ

What is the maximum continuous working voltage supported by ADUM2200BRIZ?

ADUM2200BRIZ supports a maximum continuous working voltage of 645 V_peak (reinforced insulation per DIN EN IEC 60747-17), corresponding to 456 V_rms. This rating applies to bipolar waveforms and is validated for use in medical (IEC 60601-1), industrial (IEC 62368-1), and test equipment (IEC 61010-1) applications where sustained high-voltage isolation is required. The ADUM2200BRIZ must be operated within its recommended conditions to maintain this rating.

Does ADUM2200BRIZ support bidirectional communication on each channel?

No, ADUM2200BRIZ provides two unidirectional channels only: Channel A (VIA → VOA) and Channel B (VIB → VOB). It does not support true bidirectional data flow per pin. For bidirectional isolation (e.g., I²C), external logic or a dedicated bidirectional isolator like ADUM1250 is required. The ADUM2200BRIZ pinout and internal architecture are fixed for input-to-output directionality, as confirmed in the functional block diagram and pin descriptions.

What is the purpose of the refresh circuit in ADUM2200BRIZ?

The refresh circuit in ADUM2200BRIZ continuously monitors idle input states and retransmits static logic levels across the isolation barrier to guarantee DC correctness during prolonged signal inactivity, power-up, or power-down sequences. This eliminates output uncertainty without requiring external clocking or protocol-level handshaking - a key advantage over optocouplers and some capacitive isolators. The ADUM2200BRIZ refresh operates autonomously at ~1.2 Mbps and requires no user configuration.

Can ADUM2200BRIZ operate with different supply voltages on each side?

Yes, ADUM2200BRIZ supports mixed-supply operation: VDD1 and VDD2 may be independently set between 3.0 V and 5.5 V, enabling seamless 3.3 V ↔ 5 V level translation. For example, VDD1 = 5.0 V and VDD2 = 3.3 V is fully characterized per Tables 7–8, with verified timing, current consumption, and noise immunity. This capability is intrinsic to the ADUM2200BRIZ architecture and does not require external level-shifting components.

Which safety certifications apply to ADUM2200BRIZ in the RI-16-2 package?

ADUM2200BRIZ in the RI-16-2 package is certified to UL 1577 (5000 V_rms), IEC/EN/CSA 62368-1, IEC/CSA 60601-1 (2 MOPP), IEC/CSA 61010-1, CQC GB4943.1, and DIN EN IEC 60747-17 (VDE 0884-17) with VIORM = 645 V_peak. These approvals are explicitly listed for the RI-16-2 variant in Table 14 and confirmed by certificate numbers including CQC14001105917 and 40011599. The ADUM2200BRIZ marking includes an asterisk (*) denoting VDE 0884-17 compliance.
