Current-Sense Amplifiers (CSAs)

Maxim offers more families of current-sense amplifiers than anyone else in the industry. Use our Current-Sense Error Budget Calculator to save time and effort.

Low Supply Current	Low Offset Voltage (High Precision)	Wide Input Common Mode Voltage Range
< 100µA < 500µA < 1mA	< 250µV < 500µV < 1mV	> 60V > 28V

Select a current-sense amplifier using our parametric tool.

You can gain many design advantages by selecting the high-side CSA architecture over a low-side CSA or a discrete solution. These include common-mode voltages of up to 76V, protection from shorts to ground, and the availability of a low-leakage shutdown mode of operation.
