Overview

  • Low 1.8V Supply Rail Over the -40°C to +125°C Range
  • 1.7V Supply Rail Over 0°C to 70°C Range
  • 15MHz Unity-Gain Bandwidth
  • Low 12.7nV/√Hz Input Voltage-Noise Density
  • Low 50µV (max) Input Offset Voltage at +25°C
  • 500fA Low Input Bias Current
  • 750µA Quiescent Current
  • < 1µA Supply Current in Shutdown
  • Low 105dB Total Harmonic Distortion

The MAX44290 offers a unique combination of high- speed, precision, and low-voltage operation, making it ideally suited for a large number of signal-processing functions, such as filtering and amplification of signals in portable and industrial equipment.

This amplifier features an input offset of less than 50μV and a high gain bandwidth product of 15MHz while maintaining a low 1.8V supply rail. The devices’ rail-to-rail input/outputs and low noise guarantee maximum dynamic range in demanding applications such as 12-to-14-bit SAR ADC drivers. Unlike traditional rail-to-rail input structures, input crossover distortion is absent due to an optimized input stage with an ultra-quiet charge pump.

The device includes a fast-power-on shutdown mode for further power savings. The operational amplifier operates from a supply range of 1.8V to 5.5V over the -40°C to +125°C temperature range and can operate down to 1.7V over the 0°C to +70°C temperature range. It is available in a tiny 6-bump wafer level package (WLP), with 0.4mm-pitch.

Product Details

The MAX44290 evaluation kit (EV kit) provides a proven design to evaluate the MAX44290 low-offset, low-power, rail-to-rail I/O operational amplifier in 6-pin wafer-level package (WLP). The EV kit circuit is preconfigured as noninverting amplifiers, but can be adapted to other topologies by changing a few components.

The EV kit comes with a MAX44290ANT+ installed.
