What this dual op-amp brings to the board
The Maxim Integrated MAX4168EUB+T is a dual general-purpose operational amplifier in a 10-pin uMAX/uSOP package. Supply range spans 2.7 V to 6.5 V, so it runs on a single 3.3 V or 5 V rail without a negative supply.
Supply voltage and temperature — where it fits
Operating from 2.7 V to 6.5 V, this part works on 3.3 V and 5 V rails common in industrial control, sensor interfaces, and battery-powered equipment. Input bias current is 50 nA typical, and input offset voltage is 350 µV — adequate for general-purpose signal conditioning but not precision instrumentation.
Housed in a 10-TFSOP / 10-MSOP (3.00 mm width) package, the MAX4168EUB+T uses the 10-uMAX/uSOP footprint. The supplier device package is 10-uMAX/uSOP. Surface-mount only; no through-hole variant exists.
For dual-sourcing, the closest pin-compatible alternative within the same family would be a part with identical package and supply range — verify the GBW and output current tradeoffs against your load.
