Dual micropower op-amp for battery and sensor front ends
The Maxim Integrated MAX4163ESA+ is a dual, general-purpose operational amplifier in an 8-SOIC package, designed for low-power and single-supply applications. It delivers a gain-bandwidth product of 200 kHz with a supply current of just 25 µA per channel, making it a strong fit for battery-powered instrumentation, portable medical devices, and always-on sensor conditioning circuits where every microamp counts. The rail-to-rail output stage allows the output to swing within millivolts of the supply rails. The input offset voltage is rated at 500 µV, and input bias current is 1 pA.
Package and mounting
The 200 kHz gain-bandwidth product sets the usable small-signal bandwidth. The 0.115 V/µs slew rate limits large-signal response.
Supply range and temperature grade
The MAX4163ESA+ operates from a single supply as low as 2.5 V up to 10 V. The -40°C to +85°C industrial temperature range suits outdoor telecom and factory-floor sensors. Output current is rated at 15 mA per channel.
Active production, no obsolescence concern
It is also ROHS3 compliant, so it meets the latest EU restriction requirements for lead-free assembly. For a BOM line that needs a stable, long-availability dual op-amp, this part presents no supply-chain risk from end-of-life.
