SP Amp ISOL Amp Single 5.5V 8-Pin Stretched SOIC W Tube
Si8921/22 devices are galvanically isolated analog amplifiers. The low voltage, differential input range allows for reduced power loss when sensing current across a shunt resistor. The output is a differential analog signal amplified to a peak 2.5V full scale output. The very low signal delay allows control systems to respond quickly to fault conditions or changes in load. Low offset and gain drift ensure that accuracy is maintained over the entire operating temperature range of -40 to +125˚C. Exceptionally high common mode transient immunity results in accurate measurements even in the presence of high-power switching.
Key Features and Benefits
- • Low offset and gain errors enable precise measurements for accurate control
- • Low offset and gain drifts allow for stable measurements across high temperature environments, typical for high power systems such motor control
Applications
- • EV/HEV OBC and DC-DC converters and BMS
- • Variable frequency drive motor control
