The 63 V/µs slew rate supports full-power bandwidth into the low-MHz range without slew-induced distortion. ## Supply current and output drive — power budget reality Each amplifier draws 1.4 mA quiescent, so the full quad package consumes 5.6 mA idle — modest for a 125 MHz part, but not micropower. The 170 mA per-channel output current is unusually high for a general-purpose op-amp; if you need to drive a 32 Ω headphone or a long cable, this part can do it without an external buffer. However, at 170 mA per channel on all four amplifiers, total package dissipation can exceed 800 mW — the 14-TSSOP's thermal resistance (about 150 °C/W) means the junction can hit 125 °C at 5.6 mA idle plus moderate output current. A thermal pad or airflow is advisable for sustained high-current operation. ## Temperature range and environment The 125°C upper limit is the junction temperature — derating applies above 85°C ambient if output current is high. ## Second-source and cross-reference The AD8040ARU has no official second-source from another manufacturer. The AD8030ARJZ-REEL7 is a dual-channel variant (2 circuits instead of 4) in a smaller SOT-23 package, useful if only two amplifiers are needed and board space is tight.","metaTitle":"AD8040ARU Quad Rail-to-Rail Op-Amp, 125 MHz, 63 V/µs","metaDescription":"AD8040ARU quad general-purpose op-amp: 125 MHz bandwidth, 63 V/µs slew rate, rail-to-rail output, 170 mA drive, -40°C to 125°C.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":"RoHS non-compliant","productStatus":"Active","categoryPath":["Logic ICs"],"specifications":{"Package":"Bulk","Slew Rate":"63V/µs","Output Type":"Rail-to-Rail","Mounting Type":"Surface Mount","-3db Bandwidth":"125 MHz","Amplifier Type":"General Purpose","Package / Case":"14-TSSOP (0.173\\\", 4.40mm Width)","lifecycle_stage":"eol_hot","Current - Supply":"1.4mA (x4 Channels)","Number of Circuits":"4","Current - Input Bias":"700 nA","Operating Temperature":"-40°C ~ 125°C","Voltage - Input Offset":"1.6 mV","Supplier Device Package":"14-TSSOP","Current - Output / Channel":"170 mA","Voltage - Supply Span (Max)":"12 V","Voltage - Supply Span (Min)":"2.7 V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$2.51","stockQuantity":0,"priceTiers":[{"qty":120,"price":"$2.51000","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/245a12f253317005aa1895173885c01a.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Is AD8040ARU RoHS compliant?","answer":"No, the AD8040ARU is listed as RoHS non-compliant.
