The 3 V to 30 V supply span lets it run from a 5 V logic rail or a 24 V industrial bus without an extra regulator. The 800 kHz gain-bandwidth product sets the usable small-signal frequency range. For a closed-loop gain of 10, the -3 dB bandwidth drops to about 80 kHz — fine for audio, low-frequency sensor amplification, or active filtering below 100 kHz. The 0.4 V/µs slew rate limits large-signal response: a 10 V peak-to-peak output swing slews in about 25 µs, so this part is not suited for fast ADC drivers or high-speed comparator applications. The 20 nA input bias current and 500 µV input offset voltage are typical for a general-purpose bipolar stage, adequate for non-critical DC accuracy in temperature monitoring or current-sense post-amplification. The TS321ID operates from a single supply as low as 3 V or as high as 30 V, and can also run on dual supplies (±1.5 V to ±15 V). The 40 mA output current per channel can drive moderate loads like a headphone amplifier, an analog meter, or the input of a downstream ADC. The 8-SOIC footprint is a standard industry package — the same land pattern as an LM358 or MCP6001 in SOIC-8, so it drops into existing layouts with no board change. ## Lifecycle and sourcing The active lifecycle means no supply-chain urgency for new designs, though the standard 8-SOIC package and single-channel count make it a straightforward drop-in for any general-purpose op-amp socket.","metaTitle":"ST TS321ID Op Amp, 800 kHz GBW, 8-SOIC, Active","metaDescription":"ST TS321ID general-purpose op-amp: 800 kHz GBW, 0.4 V/µs slew rate, 3-30 V supply, -40 to 125°C, 8-SOIC.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Logic ICs"],"specifications":{"Package":"Tube","Slew Rate":"0.4V/µs","Mounting Type":"Surface Mount","Amplifier Type":"General Purpose","Package / Case":"8-SOIC (0.154\\\", 3.90mm Width)","lifecycle_stage":"eol_hot","Current - Supply":"600µA","Number of Circuits":"1","Current - Input Bias":"20 nA","Operating Temperature":"-40°C ~ 125°C","Gain Bandwidth Product":"800 kHz","Voltage - Input Offset":"500 µV","Supplier Device Package":"8-SOIC","Current - Output / Channel":"40 mA","Voltage - Supply Span (Max)":"30 V","Voltage - Supply Span (Min)":"3 V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$1.02","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$1.02000","currency":"USD"},{"qty":10,"price":"$0.91600","currency":"USD"},{"qty":25,"price":"$0.86960","currency":"USD"},{"qty":100,"price":"$0.71430","currency":"USD"},{"qty":250,"price":"$0.66776","currency":"USD"},{"qty":500,"price":"$0.59010","currency":"USD"},{"qty":1000,"price":"$0.46587","currency":"USD"},{"qty":2500,"price":"$0.43950","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/4e4e2e60f32c6a79c0e6c791ee861255.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the TS321ID equivalent or recommended replacement?","answer":"No direct pin-compatible replacement is listed by STMicroelectronics.
