Product details

22 MHz GBW at 420 µA — the power-performance balance

The MAX4249ESD+ is a dual general-purpose op-amp with 22 MHz gain-bandwidth product and 2.1 V/µs slew rate, drawing 420 µA supply current for both channels.

Supply range and single-supply operation

The supply span runs from 2.4 V minimum to 5.5 V maximum. The rail-to-rail output maintains swing headroom even at the lower end of the range.

Active lifecycle and sourcing posture

The MAX4249ESD+ carries an Active product status and is ROHS3 compliant.

Frequently asked questions

Can MAX4249ESD+ be used as a replacement for LM358?

The MAX4249ESD+ is not a direct pin-for-pin replacement for the LM358 — the LM358 uses a different pinout (typically 8-pin DIP/SOIC) and has a much lower GBW (~1 MHz). The MAX4249ESD+ offers 22 MHz GBW, rail-to-rail output, and 0.1 pA input bias, which are significantly higher performance. It would require a board redesign and is best considered for new designs that need the bandwidth and low power, not as a drop-in swap.

What is the typical application of MAX4249ESD+?

Typical applications include battery-powered instrumentation, portable medical devices, sensor signal conditioning (e.g., photodiode amplifiers, thermocouple buffers), and active filters in industrial control loops. The combination of 22 MHz GBW, low 420 µA supply current, and rail-to-rail output makes it suited for single-supply 3.3 V or 5 V systems that need bandwidth without high power draw.

Is MAX4249ESD+ suitable for single-supply applications?

Yes. The supply range of 2.4 V to 5.5 V covers both 3.3 V and 5 V single-supply rails, and the rail-to-rail output allows the output to swing close to the supply rails without a negative rail.
