Precision 76V current sense amplifier for high voltage monitoring
The MAX40010 single-channel high-side precision current- sense amplifier has an input common-mode voltage range from 2.7V to 76V and accuracy of 12μV (max) on the input offset voltage and less than 0.1% (max) gain error. The precision offset and gain error allows the device to sense very small sense/shunt resistors, 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), and the current sense inputs have EMIR filters to reject RF found in communications equipment, as well as automotive sensing, energy management, solar panel monitoring and server backplanes in data centres.
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.
