Product details

Active production, wide supply range, compact SOT-23-8

With a 5 MHz gain-bandwidth product and 3 V/µs slew rate, this op-amp can handle audio-frequency signals up to several hundred kHz with minimal distortion, and can reproduce fast pulse edges in timing or level-shifting circuits. The 200 nA input bias current is moderate — high-impedance sources above 100 kΩ will see noticeable offset drift, so match source impedances or use a FET-input part.

The SOT-23-8 package (supplier device package SOT-23-8) is a compact footprint for space-constrained boards.

The part is listed as RoHS non-compliant, which matters for designs targeting EU RoHS exemptions or legacy assemblies where lead-bearing finishes are accepted. For new designs requiring RoHS compliance, check the lead-free suffix variants or plan for a waiver.

Frequently asked questions

Is MAX4494AKA rail-to-rail output?

Yes, the output type is rail-to-rail, allowing the output to swing close to both supply rails — useful for maximizing dynamic range in low-voltage single-supply designs.

What are the alternatives or equivalents for MAX4494AKA?

Within the same general-purpose dual op-amp class, parts like the Texas Instruments OPA2374 or Analog Devices AD8606 offer similar rail-to-rail output and supply range, but packaging and pinout should be verified against the MAX4494AKA's SOT-23-8 footprint.
