Silicon Labs Si8920, the Industry's Fastest Isolated Current Sense Amplifier, Now Shipping from Mouser Electronics

September 30, 2015 - Mouser Electronics, Inc. is now stocking Si8920 isolated amplifiers from Silicon Labs. The analog Si8920 amplifiers deliver robust galvanic isolation and the industry's highest bandwidth and lowest signal delay. The amplifiers' low-voltage (±100mV or ±200mV) differential input is ideal for measuring voltage across a current shunt resistor or for any place where a sensor must be isolated from the control system, such as in industrial motor drives. The AEC-Q100-compliant amplifiers are ideal for use in harsh environments such as solar inverters, high-voltage power converters, uninterruptible power supplies (UPS), and electric/hybrid-electric vehicle (EV/HEV) systems.

The Silicon Labs Si8920 isolated amplifiers, available from Mouser Electronics, use Silicon Labs' CMOS-based isolation technology, which supports up to 5 kV withstand and 1200 V working voltage, and offers a wider operating temperature range, better noise immunity, and longer lifetimes than competing isolation technologies. The amplifiers feature very low 0.75µs signal delay, allowing control systems to respond quickly to fault conditions or changes in load. The amplifiers' low 1 µV/°C offset drift ensures stable performance over the entire operating temperature range of ‑40 degrees Celsius to +125 degrees Celsius. The Si8920 amplifiers' high common-mode transient immunity maintains accurate measurements even in the presence of high-power switching. The amplifiers' industry-leading signal bandwidth (up to 750 kHz) ensures rapid, precise DC current measurement and accurate representation of the primary signal and harmonics.

Mouser is also stocking the Silicon Labs Si8920ISO-KIT evaluation kit, which helps designers test the Si8920 amplifier against a user-connected shunt resistor. The kit features test points for monitoring the inputs, outputs, and supplies for the device and includes surface mount component pads for input or output filtering circuits.
