MAX44284 - Low-Power Current-Sense Amplifier

General Description

The MAX44284 is a high-side, current-sense amplifier that operates with a 1.7V to 5.5V single supply and is optimized for very low power operation with only 21µA of quiescent current.

The MAX44284 offers precision accuracy specifications of 2μV VOS and gain error of 0.05%.

Key Features

  • an input common-mode voltage range from -0.1V to +36V. This current-sense amplifier has a voltage output and is offered in four different gain versions. The MAX44284 is offered in small 6-bump, 0.4mm-pitch WLP (1.3mm x 0.9mm) and 6-pin SOT23 packages and is specified for operation over the -40°C to +125°C automotive temperature range. Benefits and Features.
  • Very Low 2μV Input Offset Voltage (MAX44284F/H)).
  • Extremely Low 50nV/°C Input Offset Temperature Coefficient.
  • Low Supply.
