Rail-to-rail output stages let it swing to within millivolts of either supply rail, which matters when the ADC reference or comparator threshold sits near the supply. Input bias current of 1 pA keeps the part viable for photodiode transimpedance stages or high-impedance sensor buffers where a bipolar-input amp would introduce offset drift. ## Supply range and temperature grade Runs from a single 2.7 V to 5.5 V supply. The -40°C to 125°C operating range qualifies it for outdoor telecom cabinets and factory-floor I/O modules. Each channel draws 2.5 mA quiescent supply current. ## Output drive and package fit Each amplifier can source or sink 48 mA. The 8-uMAX/uSOP footprint (3.00 mm body width) fits tight mixed-signal layouts. ## Lifecycle and compliance Standard lead times apply through the franchised channel; independent inventory is also available for spot cover.","metaTitle":"MAX4477AUA+ Dual Op-Amp, 10 MHz GBW, Rail-to-Rail Output","metaDescription":"MAX4477AUA+ dual general-purpose op-amp: 10 MHz GBW, 3V/µs slew rate, rail-to-rail output, 2.7-5.5 V supply, -40°C to 125°C.

For a dual op-amp in the same 8-uMAX footprint, the ADA4891-2 from Analog Devices is a functional alternative with similar 10 MHz GBW and rail-to-rail output, though its input bias current is higher (2 pA typical vs 1 pA). Verify the supply range and offset specs against your design before substituting."},{"question":"Can MAX4477AUA+ replace NE5532?","answer":"Not a direct pin-for-pin replacement. The NE5532 is a bipolar-input dual op-amp in an 8-pin DIP or SOIC with higher supply current and wider bandwidth, but its input bias current is orders of magnitude higher (200 nA typical vs 1 pA). The MAX4477AUA+ runs on a lower supply voltage (2.7-5.5 V vs NE5532's typical ±5 to ±15 V) and offers rail-to-rail output. For a single-supply, low-bias design the MAX4477 is a better fit; for a classic ±15 V audio circuit the NE5532 remains the standard."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/analog-devices/MAX4477AUA","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/analog-devices/MAX4477AUA when reusing this data.
