Si892x Isolated Amplifiers

Skyworks Solutions Inc. Si892x Isolated Amplifiers are designed for low-voltage differential signals and are suitable for connection to low-resistance current shunt measurement resistors. These galvanically isolated analog amplifiers offer 0.8µs low signal delay that allows control systems to respond quickly to fault conditions or changes in load. The Si8921 provides a differential output voltage, while the Si8922 provides a single-ended output voltage. The Si892x modulates the analog signal in a unique way for transmission across the semiconductor-based isolation barrier.
