The 600 µA supply current keeps the power budget lean for multi-channel or battery-powered boards. Supply range spans 3 V to 30 V single or dual supply, so it runs directly off a 5 V logic rail, a 12 V industrial bus, or a 24 V field supply without needing an extra regulator. Input bias current is 20 nA, input offset voltage 500 µV — adequate for non-critical DC accuracy in temperature monitoring, current sensing, or comparator duty. ## Temperature grade and deployment context The 40 mA output per channel can drive moderate loads like a logic input or a small relay coil directly. No rail-to-rail output — the output swing is limited by the supply rails, so budget headroom if you need to hit the full 3.3 V ADC input range from a 3.3 V supply. ## Lifecycle and sourcing posture The 8-SOIC footprint is common across many general-purpose op-amps, making it straightforward to dual-source if needed.","metaTitle":"TS321IDR General Purpose Op-Amp, 800 kHz GBW, 8-SOIC","metaDescription":"TS321IDR general-purpose op-amp from Texas Instruments. 800 kHz GBW, 0.4 V/µs slew rate, 600 µA supply, -40°C to 125°C.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Logic ICs"],"specifications":{"Package":"Tape & Reel (TR); Cut Tape (CT)","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":"$0.97","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$0.97000","currency":"USD"},{"qty":10,"price":"$0.85400","currency":"USD"},{"qty":25,"price":"$0.80160","currency":"USD"},{"qty":100,"price":"$0.65440","currency":"USD"},{"qty":250,"price":"$0.60780","currency":"USD"},{"qty":500,"price":"$0.51728","currency":"USD"},{"qty":1000,"price":"$0.41382","currency":"USD"},{"qty":2500,"price":"$0.37503","currency":"USD"},{"qty":5000,"price":"$0.36600","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/4e4e2e60f32c6a79c0e6c791ee861255.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the TS321IDR equivalent or replacement?","answer":"A functionally similar general-purpose op-amp is the TLV9351IDCKR, which offers a 3.5 MHz GBW and rail-to-rail output in a similar footprint, but with a 4.5 V minimum supply.
