Maxim Integrated — MAX40010: 76V Precision, High-Voltage, Current-Sense Amplifier

The MAX40010 is a single-channel high-side precision current-sense amplifier with an input common-mode voltage range from 2.7V to 76V, which makes it ideal for communications, automotive, data centers and other systems where high-voltage current monitoring is critical. The MAX40010 offers accuracy specifications of less than 12μV (max) input offset voltage and less than 0.1% (max) gain error. It features 80kHz of small signal bandwidth and four unique gain options (12.5V/V, 20V/V, 50V/V, and 100V/V). The device’s current sense inputs have EMIR filters to reject RF found in communications equipment.
