The MAX44246 is a 36V, ultra-precision, low-noise, low-drift, dual operational amplifier that offers 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. This dual device features rail-to-rail outputs, operates from a single 2.7V to 36V supply or dual ±1.35V to ±18V supplies, and consumes only 0.42mA per channel, with only 9nV/ input-referred voltage noise.
The IC is unity-gain stable with a gain-bandwidth product of 5MHz. With excellent specifications such as offset voltage of 5µV (max), drift of 20nV/°C (max), and 117nVP-P noise in 0.1Hz to 10Hz, the IC is 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 IC is available in 8-pin µMAX® or SO packages and is rated over the -40°C to +125°C temperature range.
