Analog Devices Inc. ADuM3195 Isolated Amplifiers

Analog Devices ADuM3195 Isolated Amplifiers use iCoupler® technology and offer exceptional stability. The Analog Devices ADuM3195 has low offset and gain errors, making them ideal for isolated voltage sensing applications. Unlike optocouplers, which can vary in performance with time and temperature, ADuM31951’s transfer functions remain consistent from -40°C to +125°C.
