The MAX44244/MAX44245/MAX44248 family of parts provide ultra-precision, low-noise, zero-drift single/quad/ dual operational amplifiers featuring very low-power operation with a wide supply range. The devices incorporate a patented auto-zero circuit that constantly measures and compensates the input offset to eliminate drift over time and temperature as well as the effect of 1/f noise. These devices also feature integrated EMI filters to reduce high-frequency signal demodulation on the output. The op amps operate from either a single 2.7V to 36V supply or dual ±1.35V to ±18V supply. The devices are unity-gain stable with a 1MHz gain-bandwidth product and a low 90µA supply current per amplifier.

The low offset and noise specifications and high supply range make the devices ideal for sensor interfaces and transmitters.

The devices are available in µMAX®, SO, SOT23, and TSSOP packages and are specified over the -40°C to +125°C automotive operating temperature range.

Applications

  • 4-20mA and 0 to 10V Transmitters
  • PLC Analog I/O Modules
  • Portable Medical Devices
  • Sensors Interfaces
  • Weight Scales

Product Detail

The MAX44248 evaluation kit (EV kit) provides a proven design to evaluate the MAX44248 low-power, dual op amps in an 8-pin µMAX® package. The EV kit circuit is preconfigured as noninverting amplifiers, but can be adapted to other topologies by changing a few components. The component pads use a 0805 package, making them easy to solder and replace. The EV kit comes with a MAX44248AUA+ installed.

Applications

  • 4-20mA and 0 to 10V Transmitters
  • PLC Analog I/O Modules
  • Portable Medical Devices
  • Sensors Interfaces
  • Weight Scales
