The MAX44285LAWA+T: The 80 kHz -3dB bandwidth sets the practical upper frequency for accurate gain — above that the response rolls off, so this part suits DC and low-frequency AC current monitoring in power supplies, motor drives, and battery-management systems where the load dynamics stay below a few tens of kilohertz. The 12 µV input offset voltage keeps the error small at low shunt drops, which is the key spec when you are sensing milliohm shunts at amp-level currents.
Supply span and temperature range
Input bias current is 65 µA per amplifier, which loads the shunt slightly — factor that into the shunt value calculation if you are measuring microamp-level currents.
Lifecycle and compliance
ROHS3 compliant.
