The MAX44250/MAX44251/MAX44252 are 20V, ultra-precision, low-noise, low-drift amplifiers that offer nearzero DC offset and drift through the use of patented auto-correlating 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, dual, and quad devices feature rail-to-rail outputs, operate from a single 2.7V to 20V supply or dual ±1.35V to ±10V supplies and consume only 1.15mA per channel, while providing 5.9nV/ input-referred voltage noise. The ICs are unity-gain stable with a gain-bandwidth product of 10MHz.
With excellent specifications such as offset voltage of 6µV (max), drift of 19nV/°C (max), and 123nVP-P noise in 0.1Hz to 10Hz, the 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 5-pin SOT23, 8-pin SOT23, 8-pin µMAX®, and 14-pin SO packages and are rated over the -40°C to +125°C temperature range.

Evaluation Kit for the MAX44251

Features and Benefits

  • Accommodates Multiple Op-Amp Configurations
  • Rail-to-Rail Inputs/Outputs
  • Accomodates Easy-to-Use 0805 Components
  • 2.7V to 20V Power-Supply Range
  • Proven PCB Layout
  • Fully Assembled and Tested

Product Detail

The MAX44251 evaluation kit (EV kit) provides a proven design to evaluate the MAX44251 dual low-power, low-drift operational amplifier (op amp) in an 8-pin SOT23 package. The EV kit circuit is preconfigured as noninverting amplifiers, but can be adapted to other topologies by changing a few components. Low power, low drift, input offset voltage, and rail-to-rail input/output stages make this device ideal for applications requiring ultra-low noise and DC precision. The component pads accommodate 0805 packages, making them easy to solder and replace. The EV kit comes with a MAX44251AKA+ installed.

Applications

  • Load Cell and Bridge Transducer Amplification
  • Medical Instrumentation
  • Precision Instrumentation
  • Pressure Transducers
  • Strain Gauges
