Product details

What this op-amp is and where it fits

The Maxim Integrated MAX4240EUK+T is a single-channel general-purpose operational amplifier from the Beyond-the-Rails™ series, housed in a SOT-23-5 package. It delivers a rail-to-rail output stage that swings within millivolts of both supply rails, maximizing dynamic range in low-voltage systems. With a gain-bandwidth product of 90 kHz and a supply current of 14 µA, this part is sized for battery-powered sensor conditioning, portable instrumentation, and single-supply signal chains where every microamp counts. The supply span from 1.8 V to 5.5 V covers single-cell Li-ion, logic, and industrial rails.

Temperature grade and environment

Rated for the -40°C to 85°C industrial temperature range, the MAX4240EUK+T suits outdoor telecom enclosures, factory-floor sensor interfaces, and automotive cabin environments that do not require AEC-Q100 qualification. The SOT-23-5 package keeps board area small, which helps in space-constrained designs like portable probes or distributed I/O modules.

Sourcing and lifecycle

The MAX4240EUK+T carries an Active lifecycle status and is ROHS3 compliant.

Frequently asked questions

What is the gain bandwidth product of MAX4240EUK+T?

The gain-bandwidth product is 90 kHz, which sets the usable frequency range for closed-loop gain configurations. At a gain of 10, the -3 dB bandwidth is approximately 9 kHz.

Is MAX4240EUK+T rail-to-rail?

Yes, the MAX4240EUK+T features a rail-to-rail output stage that swings within millivolts of both supply rails, maximizing dynamic range in low-voltage single-supply designs.

What is the closest pin-compatible alternative to MAX4240EUK+T?

Within the Beyond-the-Rails™ series, the MAX4240EUK+T is a single-channel device. A dual-channel sibling, the MAX4241, shares the same 90 kHz GBW, rail-to-rail output, and 14 µA supply current, but comes in an 8-pin package. Pin compatibility depends on the circuit count required.
