Silicon Labs has introduced a new isolated current sense amplifier with industry-leading signal bandwidth (up to 750 kHz) that ensures rapid, precise DC current measurement and accurate representation of the primary signal and harmonics. The Si8920 isolated amplifier provides an ideal current shunt measurement solution for power control systems operating in harsh environments (e.g., hybrid vehicles, industrial motor drives, and high-voltage power converters).
The Si8920 isolated amplifier uses Silicon Labs’ proven, CMOS-based isolation technology, supports up to 5 kV withstand and 1200 V working voltage, and offers a wide operating temperature range, noise immunity, and long lifetimes. With exceptionally low 1-µV/°C offset drift, you gain stable performance over diverse operating conditions.
The Si8920 isolated amplifier is available in standard SOIC and DIP packages. Pricing in 10,000-unit quantities starts at $2.39. The $29 Si8920ISO-KIT evaluation kit enables you to connect quickly to a shunt resistor to evaluate Si8920 analog isolation functionality including low-voltage differential input, response times, offset and gain characteristics.
