A 210 V/µs slew rate means this part can reproduce a 10 MHz full-scale sine wave with less than 1% distortion, so it handles video (NTSC/PAL at 6 MHz) and high-speed data converters without slewing artifacts. The 240 MHz -3 dB bandwidth gives enough gain margin for a closed-loop gain of 10 at 24 MHz, which covers most high-speed ADC front-end requirements. If your design needs to settle a 10 V step to 0.1% in under 100 ns, this part delivers that margin. Rail-to-rail output means the output swings within a few millivolts of each rail, preserving dynamic range in low-voltage systems. Input common-mode range extends from the negative rail to about 1 V below the positive rail — fine for single-supply ground-referenced signals, but if you need true rail-to-rail input, that is not this part. The 2 pA input bias current suits high-impedance sources like photodiodes or pH probes without adding offset from bias current. ## Temperature range and operating environment The SOT-23-5 package keeps board area small and is compatible with standard reflow profiles. MSL 1 out of the bag — no bake required before reflow if the pouch seal is intact. ## Lifecycle and sourcing ADI lists the ADA4891-1ARJZ-RL as an active product with no announced end-of-life. It is ROHS3 compliant and available through independent distribution. For a production BOM line, this part carries no imminent LTB risk and is suitable for new designs.","metaTitle":"ADA4891-1ARJZ-RL General Purpose Op-Amp, 240 MHz","metaDescription":"ADI ADA4891-1ARJZ-RL single CMOS op-amp: 210 V/µs slew rate, 240 MHz bandwidth, rail-to-rail output, 2.7 V to 5.5 V supply, SOT-23-5.","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":"240 MHz","Amplifier Type":"General Purpose","Package / Case":"SC-74A, SOT-753","lifecycle_stage":"eol_hot","Current - Supply":"4.4mA","Number of Circuits":"1","Current - Input Bias":"2 pA","Operating Temperature":"-40°C ~ 125°C","Voltage - Input Offset":"2.5 mV","Supplier Device Package":"SOT-23-5","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":"$1.97","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$1.97000","currency":"USD"},{"qty":10,"price":"$1.77000","currency":"USD"},{"qty":25,"price":"$1.66960","currency":"USD"},{"qty":100,"price":"$1.42240","currency":"USD"},{"qty":250,"price":"$1.33560","currency":"USD"},{"qty":500,"price":"$1.16864","currency":"USD"},{"qty":1000,"price":"$0.96831","currency":"USD"},{"qty":2500,"price":"$0.94500","currency":"USD"},{"qty":10000,"price":"$0.94500","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":"How does ADA4891-1ARJZ-RL compare to ADA4891-2?","answer":"The ADA4891-2ARZ-RL is the dual-channel version of the same amplifier core.
