What this dual op-amp brings to a high-speed signal chain
The MAX4353ESA+ is a dual general-purpose operational amplifier from Analog Devices that combines an 80 MHz -3dB bandwidth with a 240 V/µs slew rate, all while drawing just 620 µA per channel. That power-versus-speed ratio makes it a fit for portable or multichannel systems where you need to buffer fast analog signals—video lines, ADC front-ends, or waveform reconstruction—without burning through the supply budget. The rail-to-rail output stage lets it swing close to the supply rails, which matters when you are running on a 2.7 V to 5.25 V single supply and want maximum dynamic range into an ADC or a cable driver.
240 V/µs slew rate and 80 MHz bandwidth — what they mean on the bench
Slew rate is 240 V/µs. -3dB bandwidth is 80 MHz.
Supply range and output drive in a single-supply world
Supply span is 2.7 V to 5.25 V. Rail-to-rail output swings close to the rails.
Lifecycle and sourcing posture
The MAX4353ESA+ carries an active lifecycle status and is ROHS3 compliant. No direct pin-compatible second source is listed in the available cross-reference data, so if you need dual-sourcing resilience, qualify the footprint early for a potential alternate.
