It delivers a 4 MHz gain-bandwidth product with a 1.3 V/µs slew rate, and its rail-to-rail output stage swings within millivolts of both supply rails — critical for single-supply designs running from 2.7 V up to 12 V. The 80 mA output current per channel is unusually high for a general-purpose op-amp; it can directly drive LEDs, small relays, or the input of a downstream ADC without an external buffer. The -40 to 125 °C operating range qualifies it for industrial sensor interfaces, automotive cabin electronics, and outdoor telecom line cards. ## Lifecycle and sourcing — active, ROHS3, available to order The TS921IDT carries an Active product status and is ROHS3 compliant. It is sourced through independent distribution — quoted to order against an RFQ. ## Package and temperature grade — 8-SOIC, -40 to 125 °C The 8-SOIC package (0.154\" body width, 3.90 mm) is a standard footprint shared with countless op-amps, ADCs, and interface ICs — no board respin needed if swapping from a similar single-channel op-amp.","metaTitle":"STMicro TS921IDT General Purpose Op-Amp, 4 MHz","metaDescription":"TS921IDT single general-purpose op-amp from STMicroelectronics. 4 MHz GBW, 1.3 V/µs slew rate, rail-to-rail output, 80 mA output drive. -40 to 125 °C.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Memory (DRAM / SRAM / Flash / EEPROM)"],"specifications":{"Package":"Tape & Reel (TR); Cut Tape (CT)","Slew Rate":"1.3V/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":"1mA","Number of Circuits":"1","Current - Input Bias":"15 nA","Operating Temperature":"-40°C ~ 125°C","Gain Bandwidth Product":"4 MHz","Voltage - Input Offset":"3 mV","Supplier Device Package":"8-SOIC","Current - Output / Channel":"80 mA","Voltage - Supply Span (Max)":"12 V","Voltage - Supply Span (Min)":"2.7 V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$1.92","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$1.92000","currency":"USD"},{"qty":10,"price":"$1.72300","currency":"USD"},{"qty":25,"price":"$1.62520","currency":"USD"},{"qty":100,"price":"$1.38480","currency":"USD"},{"qty":250,"price":"$1.30032","currency":"USD"},{"qty":500,"price":"$1.13776","currency":"USD"},{"qty":1000,"price":"$1.07336","currency":"USD"},{"qty":2500,"price":"$1.07336","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/b0263b7924f51af70f6292045c34ffa6.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the equivalent or replacement for TS921IDT?","answer":"The TS921ID (Tube package) is electrically identical — same 4 MHz GBW, 1.3 V/µs slew rate, rail-to-rail output, and 80 mA drive.

The LM358 is a dual-channel op-amp with a wider supply range (3–32 V) and lower output current. The TS921IDT can replace one channel of an LM358 in a low-voltage, single-supply design where rail-to-rail swing and higher output drive are needed, but the pinout and supply limits must be checked."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/stmicroelectronics/TS921IDT","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/stmicroelectronics/TS921IDT when reusing this data.
