General Description

The MAX44241/MAX44243/MAX44246 are 36V, ultra precision, low-noise, low-drift, single/quad/dual operational amplifiers that offer near-zero DC offset and drift

through the use of patented chopper stabilized and auto-zeroing techniques. This method constantly measures and compensates the input offset, eliminating drift over time and temperature and the effect of 1/f noise. These single/quad/dual devices feature rail-to-rail outputs, operate from a single 2.7V to 36V supply or dual ±1.35V to ±18V supplies, and consume only 0.42mA per channel, with only 9nV/√Hz input-referred voltage noise.

The ICs are unity-gain stable with a gain-bandwidth product of 5MHz. With excellent specifications such as offset voltage of 5FV (max), drift of 20nV/NC (max), and 117nVP-Pnoise in 0.1Hz to 10Hz, these ICs are ideally suited for applications requiring ultra-low noise, and DC precision such as interfacing with pressure sensors, strain gauges, precision weight scales, and medical instrumentation. The ICs are available in 8-pin FMAXMor SO packages and are rated over the -40NC to +125NC temperature range.
