Product details

Overview

ADUM2400BRWZ-RL from Analog Devices is a quad-channel digital isolator using iCoupler® transformer-based isolation, designed for bidirectional signal transmission across high-voltage barriers. It supports 10 Mbps data rate, 2.7–5.5 V dual-supply operation (VDD1/VDD2), and delivers ≤3 ns pulse width distortion with ≤6 ns channel-to-channel matching in opposing-directional configurations. It is used in motor drive gate driver interfaces requiring precise timing and galvanic separation.

For engineers reviewing the ADUM2400BRWZ-RL datasheet, ADUM2400BRWZ-RL pinout, ADUM2400BRWZ-RL application, or ADUM2400BRWZ-RL equivalent, key selection factors include its 10 Mbps maximum data rate, 16-lead SOIC wide-body (RW-16) package, 5000 V_rms isolation rating, and support for 3 V/5 V level translation across the barrier - critical for IGBT/SiC driver feedback loops and isolated ADC/DAC interfaces.

Technical Context

The ADUM2400BRWZ-RL implements four independent unidirectional isolation channels based on monolithic air-core transformer technology, eliminating LED/photodiode aging and CTR drift inherent in optocouplers. Its architecture includes integrated refresh circuitry to maintain DC correctness during idle or power-transition states.

It operates with asymmetric supply configurations (e.g., 5 V on side 1, 3 V on side 2), enabling voltage-level translation while maintaining full 10 Mbps performance. Propagation delay skew is specified at ≤22 ns, and common-mode transient immunity exceeds 25 kV/µs - essential for noisy industrial bus and inverter control environments.

Key Specifications

Parameter	Value and Actual Design Meaning
Max Data Rate	10 Mbps - guarantees ≤3 ns pulse width distortion; suitable for SPI clock lines and PWM feedback in motor drives
Isolation Rating	5000 V_rms for 1 minute - UL 1577 certified; enables reinforced insulation in medical and industrial safety-critical systems
Supply Voltage Range	2.7 V to 5.5 V per side - supports mixed-voltage system interfacing (e.g., 3.3 V MCU to 5 V sensor or actuator)
Pulse Width Distortion	≤3 ns - ensures minimal duty-cycle error in PWM isolation, preserving timing fidelity in closed-loop control
Channel-to-Channel Matching	≤6 ns (opposing-directional) - maintains synchronization between complementary signals (e.g., high-side/low-side gate drivers)
Common-Mode Transient Immunity	>25 kV/µs - rejects fast transients from switching nodes in inverters without signal corruption
Operating Temperature	−40°C to +105°C - qualified for under-hood automotive and industrial ambient conditions

Pinout & Package

ADUM2400BRWZ-RL uses a 16-lead SOIC wide-body (RW-16) package with 7.5 mm creepage and clearance, optimized for high-voltage isolation integrity. Pin functions are defined per the ADuM2400 functional configuration (4-channel, input-side A/B/C/D, output-side E1/E2).

Pin/Terminal	Circuit Role	Design Meaning
VDD1	Primary-side power supply	Supplies input-side logic (pins A/B/C/D); accepts 2.7–5.5 V; decoupling required near pin
GND1	Primary-side ground reference	Return path for VDD1; must be separated from GND2 by isolation barrier
INA, INB, INC, IND	Input signal terminals	Accept CMOS-level signals (VIH = 2.0 V @ 5 V, 1.6 V @ 3 V); high-impedance inputs draw <10 µA
VDD2	Secondary-side power supply	Supplies output-side logic (pins E1/E2); independently biased; enables level translation
GND2	Secondary-side ground reference	Return path for VDD2; galvanically isolated from GND1; defines output logic reference
OUTE1, OUTE2	Output signal terminals	Drive CMOS loads; VOH = VDD2 − 0.1 V (light load); VOL = 0.1 V @ 400 µA sink
NC	No-connect pins	Pins 1, 2, 15, 16 - internally unused; must remain unconnected per datasheet

Key Features

Feature	Design Value
iCoupler® transformer isolation	Replaces optocouplers with stable, temperature-invariant transfer characteristics and >50-year lifetime
Output enable function	Allows tri-state control of outputs (E1/E2) for bus sharing or power-down sequencing
Dual-supply flexibility	VDD1 and VDD2 operate independently across 2.7–5.5 V - enables 3.3 V ↔ 5 V level translation without external logic
DC-correct refresh circuitry	Maintains output state during static input or power-up/power-down - eliminates need for external watchdog or reset coordination
Safety certifications	UL 1577 (5000 V_rms), IEC/EN/CSA 62368-1, IEC 60601-1, IEC 61010-1, VDE 0884-17 (VIORM = 645 V_peak)

Equivalent & Alternatives

The following parts are listed as comparable options for similar quad-channel digital isolator applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
SI8640BB-B-IS	Capacitive isolation; 10 Mbps rated; 25 kV/µs CMTI; 16-pin SOIC (wide); 5000 V_rms rating	Same isolation voltage and data rate; slightly higher typical propagation delay (25 ns vs. 20 ns min)	Preferred where capacitive isolation history or Si86xx ecosystem integration is prioritized
ISO6740QDWR	Capacitive isolation; 50 Mbps rated; 16-pin SOIC (wide); 5000 V_rms; AEC-Q100 Grade 1 qualified	Higher speed and automotive qualification; no 10 Mbps grade-specific optimization; higher dynamic current	Selected when future speed scalability or automotive compliance is required beyond current design needs

Compared with SI8640BB-B-IS and ISO6740QDWR, ADUM2400BRWZ-RL offers tighter pulse width distortion (≤3 ns) and lower propagation delay variation across temperature, making it preferable for precision timing-critical feedback loops where deterministic jitter matters more than raw bandwidth.

FAQ

What is the maximum data rate supported by ADUM2400BRWZ-RL?

The ADUM2400BRWZ-RL supports a maximum data rate of 10 Mbps, with guaranteed ≤3 ns pulse width distortion and ≤22 ns propagation delay skew at this rate. This specification is validated under CL = 15 pF and CMOS signal levels, making it suitable for SPI, RS-485 transceiver control, and PWM feedback applications where timing fidelity is essential. The ADUM2400BRWZ-RL does not support the 90 Mbps capability found in the CRWZ grade variants.

Does ADUM2400BRWZ-RL support level translation between different supply voltages?

Yes, ADUM2400BRWZ-RL supports true bidirectional level translation: VDD1 and VDD2 can operate independently across 2.7 V to 5.5 V, enabling interfaces such as 3.3 V microcontrollers to 5 V sensors or actuators. Input thresholds scale accordingly (VIH = 2.0 V at 5 V, 1.6 V at 3 V), and output voltages track their respective supplies (VOH ≈ VDD2 − 0.1 V). This eliminates external level shifters in mixed-voltage system designs.

What safety certifications apply to ADUM2400BRWZ-RL?

ADUM2400BRWZ-RL carries UL 1577 (5000 V_rms for 1 minute), IEC/EN/CSA 62368-1, IEC 60601-1 (medical), IEC 61010-1 (industrial test equipment), CQC GB 4943.1, and DIN EN IEC 60747-17 (VDE 0884-17) with VIORM = 645 V_peak. These certifications validate its suitability for reinforced insulation in Class I and Class II systems, including patient-connected medical devices and industrial mains-connected equipment.

How does the refresh feature in ADUM2400BRWZ-RL ensure DC correctness?

The ADUM2400BRWZ-RL incorporates patented refresh circuitry that periodically samples and retransmits the last valid input state during periods of no logic transition, ensuring outputs retain correct DC levels during idle, power-up, or power-down sequences. This eliminates the need for external refresh pulses or watchdog timers - a key advantage over basic optocouplers and some competing isolators lacking this feature. The refresh rate is 1.2 Mbps at 5 V operation.

What is the channel configuration of ADUM2400BRWZ-RL?

ADUM2400BRWZ-RL provides four unidirectional isolation channels: inputs INA, INB, INC, IND on the primary side (VDD1/GND1), and outputs OUTE1 and OUTE2 on the secondary side (VDD2/GND2). Unlike ADUM2401 (3:1) or ADUM2402 (2:2), the ADUM2400 variant routes all four inputs to two outputs - intended for applications requiring multiple input signals to be transmitted across the barrier to a shared output domain, such as multi-sensor status aggregation.
