Current sense amplifier, 200 kHz bandwidth, 8-SOIC
The MAX4372FESA+ is a single-circuit current sense amplifier from Analog Devices, offered in an 8-SOIC surface-mount package. It monitors current via a shunt resistor and outputs a voltage proportional to the sensed current, with a -3 dB bandwidth of 200 kHz. Supply span ranges from 2.7 V to 28 V, drawing only 30 µA quiescent current — suited for low-power rail monitoring in battery-powered or always-on systems.
Parametric fit for precision monitoring
Input offset voltage is 300 µV typical, and input bias current is 2 µA — these set the measurement floor for low-side current sensing. The 200 kHz bandwidth supports monitoring of switching transients up to that frequency. Operating temperature range of -40°C to +85°C covers industrial and automotive cabin environments. The 8-SOIC package (0.154" width, 3.90 mm) is a standard footprint for automated assembly.
Lifecycle and compliance status
The MAX4372FESA+ carries an active product status per the manufacturer. ROHS3 compliant — no restricted substances above the threshold per the current directive.
