It is designed for precision DC signal conditioning where offset drift over temperature and time would otherwise swamp the measurement — think thermocouple amplifiers, strain-gauge bridges, current-sense front-ends, and medical instrumentation that runs from a single 2.7 V to 36 V rail. The zero-drift architecture keeps input offset voltage at 2 µV typical, which means you are not spending board space on trim pots or digital calibration routines for every channel. That offset stays tight across the full -40°C to 125°C temperature range, so the part works in an engine bay or an outdoor industrial enclosure without accuracy walking away as the sun heats the panel. ## Slew rate and bandwidth — what they mean for your signal The 0.7 V/µs slew rate and 1 MHz gain-bandwidth product tell you this is a DC-precision part, not a high-speed amplifier. Use it where the signal bandwidth stays under a few tens of kilohertz — that covers most sensor outputs, thermocouples, RTDs, and bridge circuits. The 40 mA output current per channel is enough to drive a reference input, a modest headphone load, or the analog input of a typical microcontroller ADC. It is not a line driver or a power buffer — keep the load impedance above a few hundred ohms if you want the rail-to-rail swing to hold. ## Package and supply flexibility for the BOM Input bias current is 150 pA typical, which is low enough for high-impedance sources like pH probes or photodiode amplifiers, provided you keep the source impedance under a few megaohms. ## Lifecycle and sourcing — active, no LTB risk The MAX44245AUD+T carries an Active lifecycle status and is ROHS3 compliant. That means you can qualify it into a new design today without worrying about a forced redesign two years from now.","metaTitle":"MAX44245AUD+T Zero-Drift Op-Amp, Quad, 1 MHz, 14-TSSOP","metaDescription":"MAX44245AUD+T quad zero-drift op-amp, 2 µV offset, 0.7 V/µs slew rate, rail-to-rail output, 2.7-36 V supply, -40 to 125°C.

The supply voltage range is 2.7 V to 36 V, and the output is rail-to-rail, so it runs cleanly on a single positive supply.

A direct same-function peer would be another quad zero-drift op-amp in a TSSOP-14 package, such as the ADA4522-4 from Analog Devices or the OPAx388 series from Texas Instruments — but verify pin compatibility against your specific layout before swapping.
