With a 1 MHz gain-bandwidth product and a 0.5 V/µs slew rate, it is suited for audio-frequency signal conditioning, active filtering, and sensor buffering tasks where the signal bandwidth stays below a few hundred kilohertz. ## 1 MHz GBW and 0.5 V/µs slew rate set the dynamic ceiling The 1 MHz gain-bandwidth product means the open-loop gain drops to unity at 1 MHz; at a closed-loop gain of 10, the usable bandwidth is roughly 100 kHz. The 0.5 V/µs slew rate limits the large-signal output swing — a 10 V peak-to-peak step slews in about 20 µs, so the amplifier cannot reproduce a full-amplitude 20 kHz sine wave without distortion. Input offset voltage is 1 mV typical, and input bias current is 200 nA typical — adequate for DC-coupled stages with source impedances below 50 kΩ. Each channel draws 3 mA from the supply, keeping the total quiescent current at 6 mA for both amplifiers. The supply span ranges from a minimum of 36 V to a maximum of 36 V — this is a single-value entry in the record, meaning the part is specified for a single-ended or split supply up to ±18 V. Operating temperature is 0°C to 70°C, the commercial grade, so it belongs in benchtop or indoor equipment, not under-hood or outdoor enclosures. ## Through-hole DIP-8 for prototyping and legacy board repair Housed in an 8-DIP (0.300-inch, 7.62 mm) package with a PDIP-8 footprint, the LM1458N/NOPB is a through-hole part that fits breadboards, prototyping sockets, and existing PCB layouts designed for the standard dual op-amp pinout (pins 1–4 for amplifier A, pins 5–8 for amplifier B). The tube packaging (50 units per tube) is the standard through-hole shipping format for hand-insertion or low-volume assembly.","metaTitle":"Texas Instruments LM1458N/NOPB Dual Op-Amp, 1 MHz, 8-DIP","metaDescription":"Texas Instruments LM1458N/NOPB dual general-purpose op-amp in 8-DIP through-hole package. 1 MHz GBW, 0.5 V/µs slew rate, 3 mA supply per channel.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Memory (DRAM / SRAM / Flash / EEPROM)"],"specifications":{"Package":"Tube","Slew Rate":"0.5V/µs","Mounting Type":"Through Hole","Amplifier Type":"General Purpose","Package / Case":"8-DIP (0.300\\\", 7.62mm)","lifecycle_stage":"eol_hot","Current - Supply":"3mA (x2 Channels)","Number of Circuits":"2","Current - Input Bias":"200 nA","Operating Temperature":"0°C ~ 70°C","Gain Bandwidth Product":"1 MHz","Voltage - Input Offset":"1 mV","Supplier Device Package":"8-PDIP","Voltage - Supply Span (Max)":"36 V","Voltage - Supply Span (Min)":"36 V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$1.42","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$1.42000","currency":"USD"},{"qty":10,"price":"$1.27300","currency":"USD"},{"qty":25,"price":"$1.20800","currency":"USD"},{"qty":100,"price":"$0.99230","currency":"USD"},{"qty":250,"price":"$0.92756","currency":"USD"},{"qty":500,"price":"$0.81970","currency":"USD"},{"qty":1000,"price":"$0.64713","currency":"USD"},{"qty":2500,"price":"$0.61050","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/7b0fb07bd6c96757a09b5b8f7bc792ea.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is LM1458N/NOPB's listed slew rate and gain-bandwidth?","answer":"The slew rate is 0.5 V/µs and the gain-bandwidth product is 1 MHz.
