Its 4/3 input-side/side-2 split maps directly to the four standard SPI signals (SCLK, MOSI, MISO, SS) plus three additional control or interrupt lines, so you don't waste channels or need a second device. The magnetic coupling technology provides 3750Vrms isolation, and the 2 Mbps data rate supports SPI clock speeds up to roughly 2 MHz — adequate for most sensor readouts, ADC conversions, and configuration registers in industrial and motor-drive applications. ## 3750Vrms and 25 kV/µs CMTI — what they mean on the board The 3750Vrms isolation rating is the basic safety barrier for reinforced insulation in many industrial and medical designs. The 25 kV/µs common-mode transient immunity is the spec that matters when the isolator straddles a noisy power stage — a motor-drive inverter, a switching power supply, or a battery charger. Fast voltage swings across the barrier can couple through a weaker isolator and corrupt the SPI data; the ADUM3152ARSZ's CMTI rating keeps the data path clean through those transients. The 25 ns max propagation delay (both directions) is tight enough for back-to-back SPI transactions without adding a clock-stretching penalty. ## Supply range and dual-voltage operation The part operates from 3V to 5.5V on each side independently, so you can run the controller side at 3.3V and the isolated peripheral side at 5V — or any combination within that range. This is common in systems where the MCU is 3.3V but the isolated ADC or sensor runs on a 5V rail. No external isolated DC-DC is required for the isolator itself (the Isolated Power spec is No), but the load-side circuitry may still need its own isolated supply. ## Temperature range and deployment environments The rise/fall time of 2.5 ns typical keeps signal edges sharp enough for 2 Mbps SPI without excessive ringing, provided the layout keeps trace lengths short. ## Lifecycle and sourcing It is an Analog Devices original, not a second-source clone. No last-time-buy or phase-out notice is in effect.","metaTitle":"ADUM3152ARSZ SPI Digital Isolator, 3750Vrms, 7-Ch, 20-SSOP","metaDescription":"ADUM3152ARSZ SPI digital isolator from ADI, 3750Vrms isolation, 7 unidirectional channels, 2 Mbps data rate, -40°C to 125°C, 20-SSOP.","metaKeywords":null},"attributes":{"series":"iCoupler®, SPIsolator™","packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Digital Isolators"],"specifications":{"Type":"SPI","Series":"iCoupler®, SPIsolator™","Package":"Tube","Data Rate":"2Mbps","Technology":"Magnetic Coupling","Channel Type":"Unidirectional","Mounting Type":"Surface Mount","Isolated Power":"No","Package / Case":"20-SSOP (0.209\\\", 5.30mm Width)","lifecycle_stage":"eol_hot","Voltage - Supply":"3V ~ 5.5V","Number of Channels":"7","Voltage - Isolation":"3750Vrms","Operating Temperature":"-40°C ~ 125°C","Inputs - Side 1/Side 2":"4/3","Rise / Fall Time (Typ)":"2.5ns, 2.5ns","Supplier Device Package":"20-SSOP","Pulse Width Distortion (Max)":"3ns","Propagation Delay tpLH / tpHL (Max)":"25ns, 25ns","Common Mode Transient Immunity (Min)":"25kV/µs"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$6.71","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$6.71000","currency":"USD"},{"qty":10,"price":"$6.05800","currency":"USD"},{"qty":25,"price":"$5.77680","currency":"USD"},{"qty":100,"price":"$5.01590","currency":"USD"},{"qty":250,"price":"$4.79044","currency":"USD"},{"qty":500,"price":"$4.36774","currency":"USD"},{"qty":1000,"price":"$3.80416","currency":"USD"},{"qty":2500,"price":"$3.66327","currency":"USD"}]},"links":{"datasheetUrl":"https://www.analog.com/media/en/technical-documentation/data-sheets/ADuM3151_3152_3153.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Does ADUM3152ARSZ require an external isolated power supply?","answer":"No. The ADUM3152ARSZ does not include an integrated isolated DC-DC converter. It requires separate supply voltages on each side (3V to 5.5V), but those supplies do not need to be isolated from each other — the isolator itself provides the isolation. Any external circuitry on the isolated side, however, will need its own isolated power if it draws more than the signal pins can source."},{"question":"Can ADUM3152ARSZ be used with 5V and 3.3V sides?","answer":"Yes. The supply range on each side is 3V to 5.5V independently. You can run side 1 at 3.3V and side 2 at 5V, or any other combination within that range.
