The slew rate limits large-signal swing: a 10 V peak-to-peak output slews at about 33 kHz before distortion sets in. This suits low-frequency loops — thermocouple amplifiers, 4-20 mA transmitters, and PWM-filter stages — not audio or high-speed ADC drivers. ## Supply current and output drive Each channel draws 500 µA supply current, keeping the total quiescent draw at 1 mA for the dual package. The 3 V to 26 V supply span covers common industrial rails — 5 V, 12 V, and 24 V — without a secondary regulator. ## Input offset and bias — DC accuracy For a non-inverting amplifier with 10 kΩ source impedance, the offset error from bias current is 0.2 mV — negligible against the 3 mV offset. This is adequate for 8-bit precision loops; for 12-bit or better, a precision op-amp with sub-mV offset is needed. ## Packaging and lifecycle The base product number LM2904 covers a family of dual op-amps; the DRG4 suffix denotes the SOIC-8 package and the lead-free / RoHS-compliant finish (G4).","metaTitle":"LM2904DRG4 Dual General-Purpose Op-Amp, 700 kHz","metaDescription":"Texas Instruments LM2904DRG4 dual general-purpose op-amp in SOIC-8. 700 kHz GBW, 0.3 V/µs slew rate, 500 µA supply per channel.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Analog & Data Acquisition"],"specifications":{"Mfr":"Texas Instruments","Series":"-","Packaging":"Tape & Reel (TR) Cut Tape (CT)","Slew Rate":"0.3V/µs","Output Type":"-","Part Status":"Obsolete","Mounting Type":"Surface Mount","Amplifier Type":"General Purpose","Package / Case":"8-SOIC (0.154\\\", 3.90mm Width)","lifecycle_stage":"eol_hot","Current - Supply":"500µA (x2 Channels)","Number of Circuits":"2","Base Product Number":"LM2904","Current - Input Bias":"20 nA","Operating Temperature":"-40°C ~ 125°C (TA)","Gain Bandwidth Product":"700 kHz","Voltage - Input Offset":"3 mV","Supplier Device Package":"8-SOIC","Current - Output / Channel":"40 mA","Voltage - Supply Span (Max)":"26 V","Voltage - Supply Span (Min)":"3 V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.3300","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/eb5c44b8b16da183125731c110fad94c.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/LM2904DRG4/alternatives.json"},"ai":{"faq":[{"question":"Can the LM2904DRG4 replace the LM2904DR?","answer":"The LM2904DRG4 is the lead-free / RoHS-compliant version of the LM2904DR.
