The rail-to-rail output stage lets you swing close to the supply rails, which matters when you are running from a 3.3 V or 2.5 V rail and need every bit of headroom for the ADC input range. ## Package and mounting The gain-bandwidth product of 90 kHz and slew rate of 0.04 V/µs tell you this is a DC-to-slow-signal part. Do not try to push audio or fast sensor edges through it — the bandwidth simply is not there. What it does well is amplify thermocouple outputs, strain-gauge bridge signals, or any low-frequency transducer where the trade-off is supply current versus speed. The 200 µV input offset is decent for a micropower amplifier and will not require a trim pot in most production builds. Runs on anything from 2.4 V to 5.5 V, so it works straight off a single lithium cell or a regulated 5 V rail. The 8-SOIC footprint is a standard layout; the tube shipment means pick-and-place lines will need to transfer to tape if they are set up for reel feed.","metaTitle":"MAX4042ESA+ Dual Op-Amp, 90 kHz GBW, Rail-to-Rail Output","metaDescription":"MAX4042ESA+ general-purpose dual op-amp from Maxim Integrated. 90 kHz GBW, 0.04V/µs slew rate, rail-to-rail output, 2.4V to 5.5V supply.
