Its 900 kHz gain bandwidth product and 0.4 V/µs slew rate cover audio-band filtering, sensor buffering, and general-purpose signal conditioning up to a few hundred kilohertz. The CMOS input stage draws only 1 pA input bias current, preserving signal integrity from high-impedance sources like photodiodes or pH probes. The 8-UFDFN exposed-pad package (VSON008X2030, 2 mm × 3 mm body) keeps board area small; the exposed pad needs a thermal via to the ground plane for rated output current of 12 mA per channel. Active lifecycle status means no near-term end-of-life risk for production builds. The part is ROHS3 compliant, with no exemption flags.","metaTitle":"BU7242SNUX-TR CMOS Dual Op-Amp, 900 kHz GBW, Rail-to-Rail","metaDescription":"ROHM BU7242SNUX-TR dual CMOS op-amp: 900 kHz GBW, 0.4 V/µs slew rate, rail-to-rail output, 1.8 V to 5.5 V supply, -40°C to 105°C.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Discrete Semiconductors"],"specifications":{"Package":"Tape & Reel (TR); Cut Tape (CT)","Slew Rate":"0.4V/µs","Output Type":"Rail-to-Rail","Mounting Type":"Surface Mount","Amplifier Type":"CMOS","Package / Case":"8-UFDFN Exposed Pad","lifecycle_stage":"eol_hot","Current - Supply":"180µA","Number of Circuits":"2","Current - Input Bias":"1 pA","Operating Temperature":"-40°C ~ 105°C","Gain Bandwidth Product":"900 kHz","Voltage - Input Offset":"1 mV","Supplier Device Package":"VSON008X2030","Current - Output / Channel":"12 mA","Voltage - Supply Span (Max)":"5.5 V","Voltage - Supply Span (Min)":"1.8 V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.98","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$0.98000","currency":"USD"},{"qty":10,"price":"$0.87300","currency":"USD"},{"qty":25,"price":"$0.82880","currency":"USD"},{"qty":100,"price":"$0.68060","currency":"USD"},{"qty":250,"price":"$0.63624","currency":"USD"},{"qty":500,"price":"$0.56226","currency":"USD"},{"qty":1000,"price":"$0.44390","currency":"USD"},{"qty":4000,"price":"$0.41430","currency":"USD"},{"qty":8000,"price":"$0.39359","currency":"USD"},{"qty":12000,"price":"$0.37879","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/7c7ac6666c6323767713f2387a9af378.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Is BU7242SNUX-TR rail-to-rail?","answer":"Yes, the output type is rail-to-rail, allowing the output to swing within millivolts of both supply rails."},{"question":"What is the GBW of BU7242SNUX-TR?","answer":"The gain bandwidth product is 900 kHz, suitable for audio-band and low-frequency sensor signal chains."},{"question":"Can BU7242SNUX-TR replace BU7242 or similar dual op-amps?","answer":"The BU7242FVM-TR is a functional peer with the same 900 kHz GBW, 0.4 V/µs slew rate, and 1 pA input bias, but in an MSOP-8 package.
