Product details

Dual op-amp with rail-to-rail swing for single-supply signal chains

The Maxim Integrated MAX4477AUA+ is a dual, general-purpose CMOS op-amp delivering 10 MHz gain-bandwidth product and a 3V/µs slew rate in an 8-pin uMAX/uSOP package. 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.

Frequently asked questions

What is the closest pin-compatible alternative to MAX4477AUA+?

Within Maxim's own portfolio, the MAX4477AUA+ shares the same pinout and package as the MAX4475/MAX4476 single and MAX4478 quad variants, but those differ in channel count. 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.

Can MAX4477AUA+ replace NE5532?

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.
