描述 Description

The SGM8188 series is a nano-power, high precision, high-side current-sense amplifier. The device consumes only 1.2μA (MAX) quiescent current. It features a 60μV (MAX) low offset voltage, which allows for 12-bit resolution at a very low 50mV full-scale current measurement. The device can sense the voltage across a current-sense resistor in a common mode voltage range from 1.6V to 28V. The SGM8188 series provides four fixed gains: 25V/V, 50V/V, 100V/V and 200V/V, which allows flexible selection of the external current-sense resistor.
The SGM8188 is available in a Green WLCSP-1×1-4B-A package. The tiny package makes the device an excellent choice for portable and battery-powered applications with limited size. The SGM8188 is rated over the -40℃ to +125℃ temperature range.
