The 90 MHz -3 dB bandwidth supports small-signal amplification up to the low VHF range; pair it with the 105 MHz gain-bandwidth product to estimate closed-loop bandwidth at a given gain. For a gain of 10, expect roughly 10 MHz of usable small-signal bandwidth. The rail-to-rail output stage swings within millivolts of each rail, maximising dynamic range in low-voltage systems. Each channel can deliver 125 mA, enough to drive a 50 Ω back-terminated video line or a moderate headphone load directly. ## Package and footprint The same die is also available in an 8-SOIC package (ADA4891-2ARZ-RL) for designs needing a wider body or better thermal dissipation through the SOIC footprint. ## Lifecycle and sourcing It is ROHS3 compliant. For dual-sourcing flexibility, the pin-compatible ADA4891-2ARZ-RL (SOIC-8 package) is a validated alternate; the parametric core (slew rate, bandwidth, supply range) is identical.","metaTitle":"ADA4891-2ARMZ-R7 CMOS Op-Amp, 210 V/µs Slew Rate, 8-MSOP","metaDescription":"ADI ADA4891-2ARMZ-R7 dual CMOS rail-to-rail op-amp: 210 V/µs slew rate, 90 MHz bandwidth, 2.7 V to 5.5 V supply, -40°C to 125°C.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Logic ICs"],"specifications":{"Package":"Tape & Reel (TR); Cut Tape (CT)","Slew Rate":"210V/µs","Output Type":"Rail-to-Rail","Mounting Type":"Surface Mount","-3db Bandwidth":"90 MHz","Amplifier Type":"CMOS","Package / Case":"8-TSSOP, 8-MSOP (0.118\\\", 3.00mm Width)","lifecycle_stage":"eol_hot","Current - Supply":"4.4mA (x2 Channels)","Number of Circuits":"2","Current - Input Bias":"2 pA","Operating Temperature":"-40°C ~ 125°C","Gain Bandwidth Product":"105 MHz","Voltage - Input Offset":"2.5 mV","Supplier Device Package":"8-MSOP","Current - Output / Channel":"125 mA","Voltage - Supply Span (Max)":"5.5 V","Voltage - Supply Span (Min)":"2.7 V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$2.85","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$2.85000","currency":"USD"},{"qty":10,"price":"$2.55600","currency":"USD"},{"qty":25,"price":"$2.41160","currency":"USD"},{"qty":100,"price":"$2.05460","currency":"USD"},{"qty":250,"price":"$1.92920","currency":"USD"},{"qty":500,"price":"$1.68804","currency":"USD"},{"qty":1000,"price":"$1.39867","currency":"USD"},{"qty":2000,"price":"$1.36500","currency":"USD"}]},"links":{"datasheetUrl":"https://www.analog.com/media/en/technical-documentation/data-sheets/ADA4891-1_4891-2_4891-3_4891-4.PDF","sourceUrl":null},"ai":{"faq":[{"question":"What is the equivalent part or cross reference for ADA4891-2ARMZ-R7?","answer":"The closest functional equivalent is the ADA4891-2ARZ-RL, which uses the same dual CMOS amplifier core (105 MHz GBP, 210 V/µs slew rate, rail-to-rail output) in an 8-SOIC package.
