The 10 MHz gain-bandwidth product sets the usable closed-loop gain range: at a gain of 100, the -3 dB bandwidth is about 100 kHz, adequate for most transducer conditioning and audio line-level stages. The 3 V/µs slew rate supports full-power bandwidth up to roughly 48 kHz at 20 V peak-to-peak output, so it can handle fast-slewing signals without distortion in active filters or comparator-like applications. Input bias current of 25 nA is moderate — fine for resistor-divider networks, but high-impedance sources (photodiode, high-Z sensors) will see significant voltage error unless the source impedance is kept below a few hundred kilohms. The 100 µV offset is a strong point for a general-purpose part, reducing the need for a precision trim pot on the BOM. ## Package and environment The 8-DIP (0.300\" width) through-hole package is breadboard- and protoboard-friendly, and it can be hand-soldered without special equipment. The RoHS status is non-compliant, so verify your assembly's exemption policy if you are shipping to EU or RoHS-regulated markets. ## Lifecycle and sourcing posture Because it is a through-hole DIP part in an era when many op-amps have migrated to surface-mount, the supply channel is stable but lower-volume — plan your order lead time accordingly, especially if you need a multi-year commitment for a legacy BOM line.","metaTitle":"LM637CN General Purpose Op-Amp, 10 MHz GBW, 8-DIP","metaDescription":"Texas Instruments LM637CN general purpose op-amp: 10 MHz gain bandwidth, 3 V/µs slew rate, 100 µV offset, 44 V supply span.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":"RoHS non-compliant","productStatus":"Active","categoryPath":["Logic ICs"],"specifications":{"Package":"Bulk","Slew Rate":"3V/µs","Mounting Type":"Through Hole","Amplifier Type":"General Purpose","Package / Case":"8-DIP (0.300\\\", 7.62mm)","lifecycle_stage":"eol_hot","Number of Circuits":"1","Current - Input Bias":"25 nA","Operating Temperature":"-25°C ~ 85°C (TJ)","Gain Bandwidth Product":"10 MHz","Voltage - Input Offset":"100 µV","Supplier Device Package":"8-MDIP","Voltage - Supply Span (Max)":"44 V","Voltage - Supply Span (Min)":"44 V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$1.12","stockQuantity":0,"priceTiers":[{"qty":268,"price":"$1.12000","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/e412b5b642aaaaf3f1cc88bf99f093ae.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the gain bandwidth of LM637CN?","answer":"The LM637CN has a gain-bandwidth product of 10 MHz, which defines its small-signal bandwidth at unity gain."},{"question":"Is LM637CN RoHS compliant?","answer":"No, the LM637CN is listed as RoHS non-compliant.
