Each channel draws 1 µA typical supply current. ## 9 kHz GBW and 1 µA supply — the trade-off that defines the part This part is not for audio or high-speed loops; it is for DC or quasi-DC signals: temperature, pressure, strain, battery voltage, current-sense amplifier outputs. The 1 µA per-channel supply means a two-channel design adds 2 µA to the system budget, which is competitive with the lowest-power precision op-amps on the market. For comparison, the TS27L2IDT (also a dual CMOS op-amp from ST) offers 100 kHz GBW and 0.04 V/µs slew rate but draws roughly an order of magnitude more supply current — the TSU112IYST trades bandwidth for battery life. ## Automotive qualification and extended temperature range The 8-MiniSO package (3.00 mm body width, 0.118\" pitch) is a standard surface-mount footprint shared with many ST op-amps, so board layout reuse across the TSV or TS27 families is straightforward. ## Sourcing posture The TSU112IYST is an active, current-production part from STMicroelectronics. This order code is specified into the BOM against an RFQ — no allocation risk flagged on the line.","metaTitle":"TSU112IYST CMOS Op-Amp, 9 kHz GBW, AEC-Q100, 8-MiniSO","metaDescription":"STMicroelectronics TSU112IYST dual CMOS op-amp, 1 µA supply per channel, 9 kHz GBW, rail-to-rail output, AEC-Q100 qualified, -40°C to 125°C.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Analog & Data Acquisition"],"specifications":{"Grade":"Automotive","Package":"Tape & Reel (TR); Cut Tape (CT)","Slew Rate":"0.0031V/µs","Output Type":"Rail-to-Rail","Mounting Type":"Surface Mount","Qualification":"AEC-Q100","Amplifier Type":"CMOS","Package / Case":"8-TSSOP, 8-MSOP (0.118\\\", 3.00mm Width)","lifecycle_stage":"eol_hot","Current - Supply":"1µA (x2 Channels)","Number of Circuits":"2","Current - Input Bias":"1 pA","Operating Temperature":"-40°C ~ 125°C","Gain Bandwidth Product":"9 kHz","Voltage - Input Offset":"150 µV","Supplier Device Package":"8-MiniSO","Current - Output / Channel":"45 mA","Voltage - Supply Span (Max)":"5.5 V","Voltage - Supply Span (Min)":"1.5 V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$2.94","priceTiers":[{"qty":1,"price":"$2.94000","currency":"USD"},{"qty":10,"price":"$2.63600","currency":"USD"},{"qty":25,"price":"$2.49240","currency":"USD"},{"qty":100,"price":"$2.16010","currency":"USD"},{"qty":250,"price":"$2.04936","currency":"USD"},{"qty":500,"price":"$1.83890","currency":"USD"},{"qty":1000,"price":"$1.55088","currency":"USD"},{"qty":4000,"price":"$1.47333","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/1491067a081516f1a1f25bdf6703420c.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/TSU112IYST/alternatives.json"},"ai":{"faq":[{"question":"Is TSU112IYST AEC-Q100 qualified?","answer":"Yes, the TSU112IYST is AEC-Q100 qualified, making it suitable for automotive-grade applications."},{"question":"Can TSU112IYST be used in battery-powered applications?","answer":"Yes, the 1 µA supply current per channel and wide 1.5 V to 5.5 V supply range make it well suited for battery-powered sensor conditioning and monitoring circuits."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/stmicroelectronics/TSU112IYST","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/stmicroelectronics/TSU112IYST when reusing this data.
