The 150 µA supply current is the headline number for a BOM power budget: in a battery-operated design, that is roughly half the draw of a generic 1 MHz op-amp, which extends runtime without sacrificing rail-to-rail output swing. The input bias current of 0.2 pA is nearly negligible, so you can use high-impedance feedback networks without offset drift — useful for transimpedance amplifiers or precision integrators. ## Industrial temperature range and deployment context The CMOS input stage and rail-to-rail output let it interface directly with 3.3 V ADCs or microcontrollers without extra level shifting. The part is ROHS3 compliant.","metaTitle":"TI OPA342UA/2K5 CMOS Op-Amp, 1 MHz, Rail-to-Rail Output","metaDescription":"Texas Instruments OPA342UA/2K5 single CMOS op-amp: 1 MHz GBW, 150 µA supply, rail-to-rail output, 2.7-5.5 V supply.","metaKeywords":null},"attributes":{"series":"MicroAmplifier™","packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Analog & Data Acquisition"],"specifications":{"Series":"MicroAmplifier™","Package":"Bulk","Slew Rate":"1V/µs","Output Type":"Rail-to-Rail","Mounting Type":"Surface Mount","Amplifier Type":"CMOS","Package / Case":"8-SOIC (0.154\\\", 3.90mm Width)","lifecycle_stage":"eol_hot","Current - Supply":"150µA","Number of Circuits":"1","Current - Input Bias":"0.2 pA","Operating Temperature":"-40°C ~ 85°C","Gain Bandwidth Product":"1 MHz","Voltage - Input Offset":"1 mV","Supplier Device Package":"8-SOIC","Current - Output / Channel":"15 mA","Voltage - Supply Span (Max)":"5.5 V","Voltage - Supply Span (Min)":"2.7 V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.41","priceTiers":[{"qty":740,"price":"$0.41000","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/0cc6c2d290d2c781a7afec3d2459feaa.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/OPA342UA%2F2K5/alternatives.json"},"ai":{"faq":[{"question":"What does the /2K5 suffix mean in OPA342UA/2K5?","answer":"The /2K5 suffix indicates a 2500-unit Tape & Reel quantity.

It draws 600 µA per channel and operates up to 125°C. The OPA342UA/2K5 is a single-channel, lower-power alternative at 150 µA and 1 MHz GBW. Pin compatibility differs — the OPA4374 is a quad in a different package — so a direct drop-in replacement is not available, but the OPA4374 can serve as a higher-speed, higher-temperature alternative if the design can accommodate the quad footprint and higher supply current."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/OPA342UA-2K5","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/OPA342UA-2K5 when reusing this data.
