Product details
Overview
LTM2883HY-5S#PBF from Analog Devices (formerly Linear Technology) is a galvanically isolated 6-channel µModule isolator with integrated ±12.5V and 5V regulated isolated power supplies, supporting SPI interface at up to 4MHz bidirectional or 8MHz unidirectional data rates, 2500VRMS isolation rating, and operation across –40°C to +105°C. It enables robust communication in industrial PLCs, test equipment, and ground-loop-breaking sensor interfaces.
For engineers reviewing the LTM2883HY-5S#PBF datasheet, LTM2883HY-5S#PBF pinout, LTM2883HY-5S#PBF application, or LTM2883HY-5S#PBF equivalent, key selection criteria include its 5V input supply compatibility, adjustable isolated rail capability, high common-mode transient immunity (30kV/µs), and BGA-32 package with logic-side VL range of 1.62V–5.5V.
Technical Context
The LTM2883HY-5S#PBF implements transformer-based galvanic isolation using coupled inductors and an isolation power transformer, delivering 2500VRMS withstand voltage per UL1577 and 560VPEAK maximum continuous working voltage. Its architecture integrates a fully regulated isolated DC/DC converter powering three independent outputs: VCC2 (5V, ≥20mA), V+ (+12.5V, ≥20mA), and V– (–12.5V, ≥15mA), each adjustable via external resistors connected to AVCC2, AV+, and AV– pins.
It supports SPI-only communication (denoted by "S" suffix), with dedicated SCK/SDI/SDO/CS/SDOE pins on the logic side and corresponding SCK2/SDI2/SDO2/CS2 signals on the isolated side. Propagation delay is 35–100ns, rise/fall times ≤12.5ns, and output enable/disable time is 50ns - enabling deterministic timing in real-time control systems.

| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|

Key Features
| Feature | Design Value |
|---|---|
| No external components required | Complete isolation solution: integrated transformer, regulators, and digital channels eliminate discrete magnetics, LDOs, and level shifters - reduces BOM count and layout complexity. |
| Adjustable isolated power rails | VCC2, V+, and V– outputs can be precisely tuned using single external resistors - enables custom analog front-end biasing (e.g., ±10V op-amp rails) without redesign. |
| High-speed digital isolation | 10MHz logic channel bandwidth with 35–100ns propagation delay - suitable for time-critical feedback loops in servo drives and power inverters. |
| Robust ESD protection | ±10kV HBM across isolation barrier - prevents latch-up or damage during handling and system integration in factory environments. |
| Low-power shutdown mode | <10µA quiescent current when ON = low - enables energy-efficient sleep states in battery-backed or portable test instruments. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar isolated SPI interface applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ADUM6403ARWZ | Quad-channel digital isolator only; no integrated isolated power - requires external isolated DC/DC converter. | Lower integration; suitable when system already includes isolated power or needs only signal isolation. | Select when board space allows separate power conversion and higher channel count (4 vs 6) is needed. |
| ISO7841FDWR | Quad-channel isolator with integrated 5V DC/DC; no ±12.5V outputs - limited to single-rail isolated power. | Cannot power bipolar analog circuitry; best for digital-only isolation with modest load current (150mA max). | Choose when only 5V isolated power is required and cost sensitivity outweighs need for dual-polarity rails. |
Compared with ADUM6403ARWZ and ISO7841FDWR, the LTM2883HY-5S#PBF uniquely combines 6-channel SPI isolation, triple-output adjustable isolated power (5V/±12.5V), and H-grade temperature support - making it optimal for space-constrained industrial systems requiring full analog front-end biasing and deterministic timing.

FAQ
What is the input supply voltage range for LTM2883HY-5S#PBF?
The LTM2883HY-5S#PBF accepts a main input supply (VCC) of 4.5V to 5.5V, as indicated by the "-5" suffix. This is distinct from the -3 variant (3.0V–3.6V). The logic interface supply (VL) operates independently from 1.62V to 5.5V, allowing flexible interfacing with diverse host processors. Both supplies must be decoupled with 2.2µF capacitors per the datasheet layout guidelines.
Does LTM2883HY-5S#PBF support I2C communication?
No, the LTM2883HY-5S#PBF does not support I2C. The "S" in the part number denotes SPI-only functionality. For I2C support, the correct variant is LTM2883HY-5I#PBF. Attempting to use I2C signals on the LTM2883HY-5S#PBF will result in undefined behavior, as its pin mapping and internal logic are configured exclusively for SPI clock, data, chip select, and output enable signals.
How are the isolated power supplies adjusted on LTM2883HY-5S#PBF?
The LTM2883HY-5S#PBF provides three adjust pins: AVCC2 (for VCC2), AV+ (for V+), and AV– (for V–). Each references a precise internal voltage (600mV, +1.22V, and –1.22V respectively) to GND2. To adjust an output, connect a resistor divider between the output and GND2, then tie the center node to the corresponding AV pin. The datasheet provides formulas and example resistor values for target voltages such as ±10V or 3.3V.
What is the maximum load current supported by each isolated supply in LTM2883HY-5S#PBF?
The LTM2883HY-5S#PBF delivers up to 20mA from VCC2 (5V), up to 20mA from V+ (+12.5V), and up to 15mA from V– (–12.5V), all under specified line/load regulation limits. These ratings assume proper thermal management and operation within the –40°C to +105°C ambient range. Exceeding these currents degrades regulation accuracy and may trigger current limiting, especially on V– where the limit is 10–15mA depending on load conditions.
Is LTM2883HY-5S#PBF compliant with UL1577 and what isolation rating does it carry?
Yes, the LTM2883HY-5S#PBF is UL Recognized (File #E151738) per UL1577, rated for 2500VRMS isolation for one minute. It also meets IEC 60747-5-2 requirements with a maximum continuous working voltage of 560VPEAK and partial discharge performance of ≤5pC at 1050VPEAK. These certifications validate its suitability for reinforced insulation in industrial safety-critical applications.
