High-side, 76V current sense amp provides precision with small shunts
The device has accuracy specifications of less than 12 μV (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, improving system efficiencies and power dissipation through the sense element.
The MAX40010 features 80 kHz 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 comes in a 6-bump, 1 x 1.5 mm wafer-lever package (WLP) with 0.5 mm pitch and a SOT23 U6SN+1 package.
There is an accompanying evaluation kit, Max40010EVKIT, an assembled PCB that comes with the 20V/V gain-option chip.
