Wzmacniacz pomiarowy current-sense kanały: 1 +125 °C 1.7 → 5.5 V Voltage Maxim Integrated 6 -pinowy

Maxim Integrated’s 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. Maxim offers a huge range of operational amplifiers or as some people know them op amps, current-sense amplifiers, and comparators for signal conditioning, monitoring, and control applications.

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.
