This is the headline figure that decides the part's fit: a 3.6 V lithium cell driving the op-amp 24/7 consumes roughly 5 µW in the amplifier alone, which is negligible for a year-long deployment on a CR2032. Supply span runs from 2.2 V minimum to 36 V maximum — one lithium cell at end-of-discharge (2.5 V) still gives headroom, and a 24 V industrial rail is within the upper end without an external regulator. The single-channel (1-circuit) package means one op-amp per 8-SOIC footprint; a multi-channel design uses multiple devices. ## 2.7 kHz GBP — bandwidth budget for DC and low-frequency signals Gain-bandwidth product is 2.7 kHz. For a gain-of-10 stage, the closed-loop bandwidth is about 270 Hz — fine for thermocouple conditioning, strain-gauge amplification, or battery-voltage monitoring, but not for audio or switching-frequency loops. The slew rate of 0.001 V/µs sets the large-signal response: a 1 V step at the output takes roughly 1 ms to settle, which is acceptable for DC measurement but rules out pulse-width-modulated signals or fast transients. Input offset voltage is 200 µV typical — this is the DC error at the output for a unity-gain buffer. For a 10× gain stage, the output offset is 2 mV, which is within the noise floor of a 10-bit ADC on a 2.5 V reference but matters if the signal itself is in the microvolt range. Input bias current is 25 pA typical; a 1 MΩ source resistor drops 25 µV across the bias current — negligible unless the source impedance exceeds 10 MΩ. Output type is rail-to-rail — the output swings within a few millivolts of each supply rail at light load. At the rated 1.5 mA output current per channel, the rail-to-rail swing holds within about 100 mV of the rails, which preserves dynamic range in single-supply designs where the signal spans nearly the full supply range. ## Active, ROHS3, industrial temperature grade Operating temperature range is -40°C to 85°C — the industrial grade covers outdoor enclosures, engine-bay-adjacent electronics, and unconditioned factory-floor panels. The 8-SOIC package (3.90 mm width) is a standard surface-mount footprint; the supplier device package is 8-SO. The tube packaging is the factory-shipping format — for reel quantities, confirm the tape-and-reel suffix with the distributor.","metaTitle":"LT1494IS8#PBF op-amp, 2.7 kHz GBP, 1.4 µA supply, 8-SOIC","metaDescription":"Analog Devices LT1494IS8#PBF general-purpose op-amp, 2.7 kHz gain bandwidth, 1.4 µA supply current, rail-to-rail output, 8-SOIC package, active production","metaKeywords":null},"attributes":{"series":"Over-The-Top®","packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Discrete Semiconductors"],"specifications":{"Series":"Over-The-Top®","Package":"Tube","Slew Rate":"0.001V/µs","Output Type":"Rail-to-Rail","Mounting Type":"Surface Mount","Amplifier Type":"General Purpose","Package / Case":"8-SOIC (0.154\\\", 3.90mm Width)","lifecycle_stage":"eol_hot","Current - Supply":"1.4µA","Number of Circuits":"1","Current - Input Bias":"25 pA","Operating Temperature":"-40°C ~ 85°C","Gain Bandwidth Product":"2.7 kHz","Voltage - Input Offset":"200 µV","Supplier Device Package":"8-SO","Current - Output / Channel":"1.5 mA","Voltage - Supply Span (Max)":"36 V","Voltage - Supply Span (Min)":"2.2 V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$6.18","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$6.18000","currency":"USD"},{"qty":10,"price":"$5.55300","currency":"USD"},{"qty":25,"price":"$5.24960","currency":"USD"},{"qty":100,"price":"$4.54950","currency":"USD"},{"qty":300,"price":"$4.31623","currency":"USD"},{"qty":500,"price":"$3.87294","currency":"USD"},{"qty":1000,"price":"$3.26634","currency":"USD"},{"qty":2500,"price":"$3.10302","currency":"USD"}]},"links":{"datasheetUrl":null,"sourceUrl":null},"ai":{"faq":[{"question":"What supply voltage range does LT1494IS8#PBF support?","answer":"The supply span is 2.2 V minimum to 36 V maximum.
