3656HG [Texas Instruments]

The 3656 is a transformer-coupled isolation amplifier that provides both signal and power isolation using a patented modulation technique and miniature hybrid transformer. It features three-port isolation (input, output, and power) with completely independent grounds. The device includes internal isolated power that can power external circuitry at either input or output stages. Uncommitted op amps at input and output allow versatile closed-loop configurations for various isolation applications. Key characteristics include 8000V isolation test voltage, 0.5mA max leakage at 120V/60Hz, and 125dB IMR rejection at 60Hz.
