Product details

The Maxim MAX4321EUK+T is a single-supply, general-purpose operational amplifier in a SOT-23-5 package.

The 5 MHz GBP sets the usable closed-loop gain bandwidth. Rail-to-rail output means the output can swing within millivolts of each supply rail. Input bias current is 50 nA typical. Supply current of 725 µA per amplifier is moderate. It is not the lowest quiescent for always-on sensing, but it is low enough for portable gear that spends most time in sleep and wakes the amp for measurement bursts.

The SOT-23-5 footprint keeps the PCB area small.

Frequently asked questions

Does MAX4321EUK+T have rail-to-rail inputs and outputs?

The MAX4321EUK+T has a rail-to-rail output stage, but the evidence does not specify rail-to-rail inputs. The output can swing close to both supply rails, maximizing dynamic range on low-voltage supplies.
