The CMOS input stage delivers 0.2 pA input bias current, which means negligible loading on high-impedance sources like photodiodes, pH electrodes, or piezo sensors — no need for a separate buffer stage. Rail-to-rail output swing preserves dynamic range at low supply voltages — useful when driving an ADC input directly without a level shifter. The input offset voltage is 200 µV, typical for a precision CMOS amplifier at this price point, so the part fits general-purpose signal conditioning without requiring external trimming for most applications.","metaTitle":"TI OPA4345UA/2K5 CMOS Quad Op-Amp, 3 MHz, 2 V/µs, 14-SOIC","metaDescription":"Texas Instruments OPA4345UA/2K5 quad CMOS op-amp: 3 MHz GBW, 2 V/µs slew rate, 150 µA/ch supply, rail-to-rail output, 14-SOIC.","metaKeywords":null},"attributes":{"series":"MicroAmplifier™","packageCase":null,"mountingType":null,"rohsStatus":"RoHS non-compliant","productStatus":"Active","categoryPath":["Analog & Data Acquisition"],"specifications":{"Series":"MicroAmplifier™","Package":"Bulk","Slew Rate":"2V/µs","Output Type":"Rail-to-Rail","Mounting Type":"Surface Mount","Amplifier Type":"CMOS","Package / Case":"14-SOIC (0.154\\\", 3.90mm Width)","lifecycle_stage":"eol_hot","Current - Supply":"150µA (x4 Channels)","Number of Circuits":"4","Current - Input Bias":"0.2 pA","Operating Temperature":"-40°C ~ 85°C","Gain Bandwidth Product":"3 MHz","Voltage - Input Offset":"200 µV","Supplier Device Package":"14-SOIC","Current - Output / Channel":"15 mA","Voltage - Supply Span (Max)":"5.5 V","Voltage - Supply Span (Min)":"2.5 V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$1.34","priceTiers":[{"qty":224,"price":"$1.34000","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/c99be332156fb3b5a2b291e7c3094770.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/OPA4345UA%2F2K5/alternatives.json"},"ai":{"faq":[{"question":"Is OPA4345UA/2K5 RoHS compliant?","answer":"No, the OPA4345UA/2K5 is listed as RoHS non-compliant.
