Description

The MAX40010 single-channel high-side precision current- sense amplifier with an input common-mode voltage range from 2.7V to 76V, making it ideal for communications, automotive, data centers and other systems where high-voltage current monitoring is critical. The MAX40010 offer accuracy specifications of less than 12µV (max) Input Offset voltage and less than 0.1% (max) gain error. By offering precision offset and gain error specifications, the MAX40010 makes it possible to sense very small sense/shunt resistors, further improving system efficiencies and power dissipation through the sense element.

The MAX40010 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.

The MAX40010 operates over the -40°C to + 125°C temperature range and is offered in a 6-bump, 1mm x 1.5mm wafer-lever package (WLP) with 0.5mm pitch and a SOT23 U6SN+1 package.
