Dual op-amp with rail-to-rail output in 8-SOIC
The MAX4494ASA+ is a dual general-purpose operational amplifier from Maxim Integrated, delivering rail-to-rail output swing and a gain-bandwidth product of 5 MHz. Housed in an 8-SOIC package (3.90 mm width), it operates from a single 4.5 V to 11 V supply or split rails, drawing 770 µA per two channels.
Slew rate and bandwidth for signal conditioning
With a 3 V/µs slew rate and 5 MHz gain-bandwidth product, this amplifier handles sensor-conditioning and audio paths up to several hundred kHz before the large-signal bandwidth rolls off. The 300 µV input offset voltage and 200 nA input bias current suit moderate-precision applications where a precision op-amp would be overkill. Each channel can source or sink 15 mA, enough to drive a reference input or a small analog load directly. The rail-to-rail output stage maintains dynamic range when running from a 5 V single supply — useful in battery-powered or low-voltage industrial modules.
Temperature grade and supply flexibility
Rated for -40°C to 125°C, the MAX4494ASA+ covers industrial and automotive ambient conditions. The 4.5 V minimum supply span allows operation from a standard 5 V rail with headroom, while the 11 V maximum keeps it compatible with 12 V industrial supplies when derated.
