The gain-bandwidth product sits at 635 kHz with a 0.62 V/µs slew rate, which puts it squarely in the DC-to-audio-sub-band range. It is not a high-speed part — you are not driving an ADC at 100 ksps or shaping a PWM output with it. What it does well is hold a stable DC level, amplify a slow-changing bridge output, or buffer a reference voltage, all while keeping the power budget tight. The supply span runs from 4 V up to 16 V, covering the common 5 V and 12 V industrial rails, but it will not run on a 3.3 V rail — that lower limit rules it out for many modern portable or single-cell applications. Output drive is rated at 30 mA per channel, enough to swing into a typical ADC input or drive a transistor stage, but not meant for driving a headphone or a relay coil directly. Input offset voltage is 900 µV, which is adequate for general-purpose sensing but not precision DC measurement — if you need microvolt-level offset, you step up to a chopper-stabilized part. ## What the 0.7 pA input bias means for your sensor front-end The 0.7 pA input bias current is the headline differentiator here. In a photodiode amplifier with a 10 MΩ feedback resistor, that bias contributes just 7 µV of offset error — negligible. A bipolar op-amp with 100 nA bias would add a full 1 V of error across the same resistor, swamping the signal. The CMOS input stage also means the bias current stays flat over temperature, unlike a JFET input where bias doubles every 10°C. If your design has a high-source-impedance sensor and you are trying to keep the error budget under a few millivolts, this is the parameter that makes the part fit. ## Lifecycle and supply — active, no end-of-life notice ROHS3 compliant.","metaTitle":"Texas Instruments TLC27M2ACDR LinCMOS Dual Op-Amp, 635 kHz","metaDescription":"TI TLC27M2ACDR CMOS dual op-amp: 0.62 V/µs slew rate, 0.7 pA input bias, 285 µA supply, 4-16 V range, 0 to 70°C.","metaKeywords":null},"attributes":{"series":"LinCMOS™","packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Logic ICs"],"specifications":{"Series":"LinCMOS™","Package":"Tape & Reel (TR); Cut Tape (CT)","Slew Rate":"0.62V/µs","Mounting Type":"Surface Mount","Amplifier Type":"CMOS","Package / Case":"8-SOIC (0.154\\\", 3.90mm Width)","lifecycle_stage":"eol_hot","Current - Supply":"285µA (x2 Channels)","Number of Circuits":"2","Current - Input Bias":"0.7 pA","Operating Temperature":"0°C ~ 70°C (TA)","Gain Bandwidth Product":"635 kHz","Voltage - Input Offset":"900 µV","Supplier Device Package":"8-SOIC","Current - Output / Channel":"30 mA","Voltage - Supply Span (Max)":"16 V","Voltage - Supply Span (Min)":"4 V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$1.34","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$1.34000","currency":"USD"},{"qty":10,"price":"$1.19500","currency":"USD"},{"qty":25,"price":"$1.13360","currency":"USD"},{"qty":100,"price":"$0.93130","currency":"USD"},{"qty":250,"price":"$0.87056","currency":"USD"},{"qty":500,"price":"$0.76934","currency":"USD"},{"qty":1000,"price":"$0.60738","currency":"USD"},{"qty":2500,"price":"$0.57300","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/79576a9fd7fb1b2f4537fa70a0e1fb86.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the closest functional equivalent to TLC27M2ACDR?","answer":"There is no pin-compatible direct second source listed. The TLC27M2ACDR is a dual CMOS op-amp with 0.7 pA input bias and 285 µA supply current. Parts like the OPA4374AIPWT (quad CMOS, rail-to-rail, 6.5 MHz) or TLV9362IDDFR (dual general-purpose, rail-to-rail, 10.6 MHz) share the CMOS amplifier type but differ in speed, supply range, and output swing — neither is a drop-in replacement. The closest functional match would be another dual CMOS op-amp in SOIC-8 with similar bias current and supply current; verify pinout and compensation before substituting."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/TLC27M2ACDR","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/TLC27M2ACDR when reusing this data.
