Product Details

The MAX44241/MAX44243/MAX44246 are 36V, ultra- precision, low-noise, low-drift, single/quad/dual opera- tional amplifiers that offer near-zero DC offset and drift through the use of patented chopper stabilized and auto-zeroing techniques. This method constantly mea- sures 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 out- puts, 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 available in 8-pin µMAX® or SO packages and are rated over the -40°C to +125°C temperature range.

Applications

  • Battery-Powered Equipment
  • Load Cell Amplifiers
  • PLC Analog I/O Modules
  • Precision Instrumentation
  • Transducer Amplifiers
